- Block-level migration involves migrating disk blocks from a primary data store (e.g., a disk partition) to secondary media.
- a data storage system transfers blocks on a disk partition that have not been recently accessed to secondary storage, freeing up space on the disk.
- the system moves data from the database to other locations, such as other databases or storage locations.
- such expansion requires knowledge of the database, such as the database application, the database schema, and so on.
- block-level migration the system can expand or extend a database without any knowledge of the applications or schema of the database, providing for transparent migration and/or restoration of data from one storage location to another.
- the system may implement block-level migration processes as software device drivers, but may also implement block-level migration in disk hardware.
- the system can transfer or migrate certain blocks of a data object from one data store to another, such as from primary storage that contains a primary copy of the data object to secondary storage that contains or will contain a secondary copy of the primary copy of the data object.
- FIGS. 6A-6B a schematic diagram illustrating contents of two data stores before and after a block-based data migration is shown.
- a first data store 610 contains primary copies (i.e., production copies) of two data objects, a first data object 620 and a second data object 630 .
- the first data object comprises blocks A and A 1 , where blocks A are blocks that satisfy or meet certain storage criteria (such as blocks that have not been modified since creation or not been modified within a certain period of time) and blocks A′ are blocks that do not meet the criteria (such as blocks that have been modified within the certain time period).
- the second data object comprises blocks B and B′, where blocks B satisfy the criteria and blocks B′ do not meet the criteria.
- FIG. 6B depicts the first data store 610 after a block-based data migration of the two data objects 620 and 630 .
- the system only transfers the data from blocks that satisfy a criteria (blocks A and B) from the first data store 610 to a second data store 640 , such as secondary storage 642 , 644 .
- the secondary storage may include one or more magnetic tapes, one or more optical disks, and so on.
- the system maintains data in the remaining blocks (blocks A′ and B′) within the first data store 610 .
- the system can perform file system data migration at a block level, unlike previous systems that only migrate data at the file level (that is, they have a file-level granularity). By tracking migrated blocks, the system can also restore data at the block level, which may avoid cost and time problems associated with restoring data at the file level or may assist in defragmenting a storage device. Further details regarding the block-level restoration of data is be discussed herein.
- the system identifies data blocks within a data store that satisfy a certain criteria.
- the system may track data blocks and access the blocks via APIs.
- the data store may be a database associated with a file system, a SQL database, a Microsoft Exchange mailbox, and so on.
- the system may compare some or all of the blocks (or, information associated with the blocks) of the data store with predetermined criteria.
- the predetermined criteria may be time-based criteria within a storage policy or data retention policy.
- the system identifies blocks set to be “aged off” from the data store. That is, the system identifies blocks created, changed, or last modified before a certain date and time. For example, the system may review a data store for all data blocks that satisfy a criterion or criteria.
- the data store may be an electronic mailbox or personal folders (.pst) file for a Microsoft Exchange user, and the criterion may define, for example, all blocks or emails last modified or changed thirty days ago or earlier.
- the system compares information associated with the blocks, such as metadata associated with the blocks, to the criteria, and identifies all blocks that satisfy the criteria. For example, the system identifies all blocks in the .pst file not modified within the past thirty days.
- the identified blocks may include all the blocks for some emails and/or a portion of the blocks for other emails. That is, for a given email (or data object), a first portion of the blocks that include the email may satisfy the criteria, while a second portion of the blocks that include the same email may not satisfy the criteria.
- a file or a data object can be divided into parts or portions, and only some of the parts or portions change.
- the system can monitor the activity of the file system via the intermediate component 420 , (e.g., the virtual device driver).
- the system may store a data structure, such as a bitmap, table, log, and so on within the cache 530 or other memory of the intermediate component 420 , and update the bitmap whenever the file system calls the database 418 to access and update or change data blocks within the database 418 .
- the intermediate component 420 traps the command to the disk driver, where that command identifies certain blocks on a disk for access or modifications, and writes to the bitmap the changed blocks and the time of the change.
- the bitmap may include information such as an identification of changed blocks and a date and a time the blocks were changed.
- the bitmap which may be a table, data structure, or group of pointers, such as a snapshot, may also include other information, such as information that maps file names to blocks, information that maps chunks to blocks and/or file names, and so on.
- Table 1 provides entry information for a bitmap tracking the activity of a file system with the “/users” directory:
- the system would identify, in step 710 , blocks110-1000 as having satisfied the criteria.
- the system via the intermediate component 420 , can monitor what blocks are requested by a file system, and act accordingly, as described herein.
- the system transfers data within the identified blocks from the data store to a media agent, to be stored in a different data store.
- the system may perform some or all of the processes described with respect to FIGS. 1-3 when transferring the data to the media agent. For example, before transferring data, the system may review a storage policy as described herein to select a media agent, such as media agent 112 , based on instructions within the storage policy.
- the system optionally updates an allocation table, such as a file allocation table (FAT) for a file system associated with the data store, to indicate the data blocks that no longer contain data and are now free to receive and store data from the file system.
- FAT file allocation table
- the system stores data from the blocks to a different data store.
- the system via the media agent, stores the data from the blocks to a secondary storage device, such as a magnetic tape or optical disk.
- the system may store the data from the blocks in secondary copies of the data store, such as a backup copy, an archive copy, and so on.
- the system stores the data from the blocks to a storage device located near and/or associated with the data store, such as to a quick recovery volume that facilitates quick restores of data.
- the system may create, generate, update, and/or include an allocation table, (such as a table for the data store) that tracks the transferred data and the data that was not transferred.
- the table may include information identifying the original data blocks for the data, the name of the data object, the location of any transferred data blocks, and so on.
- Table 2 provides entry information for an example .pst file:
- the data for “Email2” is stored in two locations, a local data store (C:/) and an off-site data store (X:/).
- the system maintains the body of the email, recently modified or accessed, at a location within a data store associated with a file system, “C:/users/blocks101-120.”
- the system stores the attachment, not recently modified or accessed, in a separate data store, “X:/remov1/blocks1-250.”
- the table may include other information, fields, or entries not shown.
- the table may include tape identification information, tape offset information, and so on.
- Chunked file migration involves splitting a data object into two or more portions of the data object, creating an index that tracks the portions, and storing the data object to secondary storage via the two or more portions.
- the chunk-based migration provides for fast and efficient storage of a data object.
- chunk-based migration facilitates fast and efficient recall of a data object, such as the large files described herein. For example, if a user modifies a migrated file, chunk-based migration enables a data restore component to only retrieve from, and migrate back to, secondary storage the chunk containing the modified portion of the file, and not the entire file.
- chunk-based migration may collaborate with components that provide file format and/or database schema information in order to facilitate data recovery.
- the system migrates chunks of data (sets of blocks) that comprise a data object from one data store to another.
- FIG. 8 a block diagram illustrating a system 800 for providing chunk-based data migration and/or restoration is shown.
- the system 800 includes a file system 810 , a callback layer 820 , which interacts with the file system, and a device driver 830 , which reads from and writes data to a data store 840 such as removable media including magnetic tapes, optical disks, and so on. Further details with respect to the callback layer 820 will be described herein.
- a data object such as a file
- a chunk may be a logical division of a data object.
- a .pst file may include two or more chucks: a first chunk that stores data associated with an index of a user's mailbox, and one or more chunks that stores email, attachments, and so on within the user's mailbox.
- a chunk is a proper subset of all the blocks comprising a file. That is, for a file consisting of n blocks, the largest chunk of the file comprises at most n ⁇ 1 blocks.
- the system 800 may include a chunking component 815 that divides data objects, such as files, into chunks.
- the chunking component 815 may receive files to be stored in database 418 , divide the files into two or more chunks, and store the files as two or more chunks in database 418 .
- the chunking component 815 may update an index that associated information associated with files with the chunks of the file, the data blocks of the chunks, and so on.
- the chunking component 815 may perform different processes when determining how to divide a data object.
- the chunking component 815 may include indexing, header, and other identifying information or metadata in a first chunk, and include the payload in other chunks.
- the chunking component 815 may follow a rules-based process when dividing a data object.
- the rules may define a minimum or maximum data size for a chunk, a time of creation for data within a chunk, a type of data within a chunk, and so on.
- the chunking component 815 may divide a user mailbox (such as a .pst file) into a number of chunks, based on various rules that assign emails within the mailbox to chunks based on the metadata associated with the emails.
- the chunking component 815 may place an index of the mailbox in a first chunk and the emails in other chunks.
- the chunking component 815 may then divide the other chunks based on dates of creation, deletion or reception of the emails, size of the emails, sender of the emails, type of emails, and so on.
- the chunking component may divide a mailbox as follows:
- Chunks may not necessarily fall within logical divisions.
- the chunking component may divide a data object based on information or instructions not associated with the data object, such as information about data storage resources, information about a target secondary storage device, historical information about previous divisions, and so on.
- the system may perform chunking at various times or in different locations of a data storage system.
- FIG. 8 shows the chunking component 815 at file system 810
- the system may locate the chunking component at the device driver 830 , at an intermediate component, or other locations.
- the system may utilize the chunking component 815 to divide data already in secondary storage into chunks.
- a data storage system may retrieve data objects under management that were transferred to secondary storage using file-based data migration, divide the data objects into two or more chunks, and migrate the data objects based to storage using the chunk-based data migration discussed herein.
- future restoration of the data objects may be faster and easier because the data objects are divided into chunks.
- the system identifies chunks of data blocks within a data store that satisfy one or more criteria.
- the data store may store large files (>50 MB), such as databases associated with a file system, SQL databases, Microsoft Exchange mailboxes, virtual machine files, and so on.
- the system may compare some or all of the chunks (or, information associated with the chunks) of the data store with predetermined and/or dynamic criteria.
- the predetermined criteria may be time-based criteria within a storage policy or data retention policy.
- the system may review an index with the chunking component 815 when comparing the chunks with applicable criteria.
- the system transfers data within the identified chunks from the data store to a media agent, to be stored in a different data store.
- the system may perform some or all of the processes described with respect to FIGS. 1-3 when transferring the data to the media agent. For example, the system may review a storage policy assigned to the data store and select a media agent based on instructions within the storage policy.
- the system optionally updates an allocation table, such as a file allocation table (FAT) for a file system associated with the data store, to indicate the data blocks that no longer contain data and are now free to receive and store data from the file system.
- FAT file allocation table
- the system monitors the transfer of data from the file system to the data store via the callback layer 820 .
- the callback layer 820 may be a layer, or additional file system, that resides on top of the file system 810 .
- the intermediate layer 820 may intercept data requests from the file system 810 , in order to identify, track and/or monitor the chunks requested by the file system 810 and store information associated with these requests in a data structure, such as a bitmap similar to the one shown in Table 1.
- the intermediate layer 820 stores information identifying when chunks are accessed by tracking calls from the file system 810 to the data store 840 .
- Table 3 provides entry information for a bitmap tracking calls to a data store:
- the file system 810 creates a data object named “File1,” using the chunking component to divide the file into four chunks: “File1.1,” “File1.2,” “File1.3,” and “File1.4.”
- the file system 810 stores the four chunks to data store 840 on 06.04.2008.
- the file system has not accessed File1.4 since its creation, and most recently accessed the other chunks on Sep. 5, 2008.
- Table 3 may include other or different information, such as information identifying a location of the chunks, information identifying the type of media storing the chunks, information identifying the blocks within the chunk, and/or other information or metadata.
- the system stores the data from the chunks to a different data store.
- the system via the media agent, stores the data to a secondary storage device, such as a magnetic tape or optical disk.
- the system may store the data in secondary copies of the data store, such as a backup copy, and archive copy, and so on.
- the system stores the data to a storage device located near and/or associated with the data store, such as to a quick recovery volume.
- step 1010 the system, via a restore or data recovery component, receives a request to modify a file located in a data store. For example, a user submits a request to a file system to provide an old copy of a large Powerpoint presentation so the user can modify a picture located on slide 5 of 300 of the presentation.
- the data recovery component 410 works with the file system 417 and the data store 430 .
- step 1020 the system identifies one or more blocks or one or more chunks associated with the request. For example, the system looks to a table similar to Table 2, and identifies blocks associated with page 5 of the presentation and blocks associated with an table of contents of the presentation.
- step 1030 the system retrieves the identified blocks or chunks and presents them to the user. For example, the system only retrieves page 5 and table of contents of the presentation and presents the pages to the user.
- step 1040 the system, via the file system, modifies the retrieved blocks or chunks via the file system. For example, the user updates the Powerpoint presentation to include a different picture.
- step 1050 the system transfers data associated with the modified blocks or chunks to the data store. For example, the system transfers the modified page 5 to the data store.
- the system may also update a table that tracks access to the data store, such as Table 1 or Table 3.
- the system leveraging block-based or chunk-based data migration during data storage, restores only portions of data objects required by a file system.
- Such restoration can be, among other benefits, advantageous over systems that perform file-based restoration, because those systems restore entire files, which can be expensive, time consuming, and so on.
- Some files, such as .pst files, may contain large amounts of data.
- File-based restoration can therefore be inconvenient and cumbersome, among other things, especially when a user only requires a small portion of a large file.
- a user submits a request to the system to retrieve an old email stored in a secondary copy on removable media.
- the system identifies a portion of a .pst file associated with the user that contains a list of old emails, and retrieves the list. That is, the system has knowledge of the chunk that includes the list (e.g., a chunking component may always include the list in a first chunk of a data object), accesses the chunk, and retrieves the list.
- the other portions e.g., all the emails with the .pst file
- the user selects the desired email from the list.
- the system via an index that associates chunks with data (such as an index similar to Table 2), identifies the chunk that contains the email, and retrieves the chunk for presentation to the user.
- the index may include information about the chunks, information about the data objects (such as file formats, database schemas, application specific information, and so on).
- the system is able to restore the email without restoring the entire mailbox (.pst file) associated with the user. That is, although an entire data object is in storage, the system is able to retrieve a portion of the entire data object by leveraging the processes described herein.
- the words “comprise,” “comprising,” and the like are to be construed in an inclusive sense, as opposed to an exclusive or exhaustive sense; that is to say, in the sense of “including, but not limited to.”
- the word “coupled”, as generally used herein, refers to two or more elements that may be either directly connected, or connected by way of one or more intermediate elements. Additionally, the words “herein,” “above,” “below,” and words of similar import, when used in this application, shall refer to this application as a whole and not to any particular portions of this application. Where the context permits, words in the above Detailed Description using the singular or plural number may also include the plural or singular number respectively.
Abstract
Description
- This application claims priority to U.S. Patent Application No. 61/096,587, filed on Sep. 12, 2008, entitled TRANSFERRING OR MIGRATING PORTIONS OF DATA OBJECTS, SUCH AS BLOCK-LEVEL DATA MIGRATION OR CHUNK-BASED DATA MIGRATION, which is incorporated by reference in its entirety.
- Data storage systems contain large amounts of data. This data includes personal data, such as financial data, customer/client/patient contact data, audio/visual data, and much more. Computer systems often contain word processing documents, engineering diagrams, spreadsheets, business strategy presentations, email mailboxes, and so on. With the proliferation of computer systems and the ease of creating content, the amount of content in an organization has expanded rapidly. Even small offices often have more information stored than any single employee can know about or locate.
- To that end, both companies and individuals rely on data storage systems to store, protect, and/or hold old data, such as data no longer actively needed. Often, these data storage systems perform data migration, moving data from primary storage (containing actively needed data) to secondary storage (such as backup storage or archives). Typical data storage systems transfer data in the forms of files, folders, and so on. For example, the typical data storage system may transfer data from a data store associated with a user to secondary storage while maintaining the structure and application format of the files themselves.
- To restore the data, these systems then require knowledge of applications that create the data. Additionally, some files, can be very large, and restoring a large file can be costly, time consuming, and resource intensive.
- The need exists for a system that overcomes the above problems, as well as one that provides additional benefits. Overall, the examples herein of some prior or related systems and their associated limitations are intended to be illustrative and not exclusive. Other limitations of existing or prior systems will become apparent to those of skill in the art upon reading the following Detailed Description.
-
FIG. 1 is a block diagram illustrating components of a data stream utilized by a suitable data storage system. -
FIG. 2 is a block diagram illustrating an example of a data storage system. -
FIG. 3 is a block diagram illustrating an example of components of a server used in data storage operations. -
FIG. 4 is a block diagram illustrating a system for performing increment-based data migration. -
FIG. 5 is a block diagram illustrating the intermediate component ofFIG. 4 . -
FIGS. 6A and 6B are schematic diagrams illustrating a data store before and after a block-based data migration, respectively. -
FIG. 7 is a flow diagram illustrating a routine for performing block-level data migration. -
FIG. 8 is a block diagram illustrating a system for providing chunk-based data migration and/or restoration. -
FIG. 9 is a flow diagram illustrating a routine for performing chunk-level data migration. -
FIG. 10 is flow diagram illustrating a routine for block-based or chunk-based data restoration and modification. - Described in detail herein is a system and method that transfers or migrates data objects (such as files, folders, data stores, and/or discrete data component(s) by migrating segments, portions, increments, or proper subsets of the data objects. The system may transfer increments of files, folders, and other data objects from primary storage (or other sources) to secondary storage based on certain criteria, such as time-based criteria, age-based criteria, and so on. An increment may be one or more blocks of a data object, or one or more chunks of a data object, or other portions that combine to form, store, and/or contain a data object, such as a file.
- In some examples, the system performs block-based migration of data. That is, the system identifies one or more blocks of a data object that satisfy a certain criteria, and migrates the identified blocks. For example, the system may determine that a certain number of blocks of a file have not been modified or called by a file system within a certain time period, and migrate these blocks to secondary storage. The system then maintains the other blocks of the file in primary storage. In some cases, the system automatically migrates data without requiring user input. Additionally, the migration may be transparent to a user.
- In some examples, the system performs chunk-based migration of data. A chunk is, for example, a group or set of blocks. One or more chunks may comprise a file, folder, or other data object. The system identifies one or more chunks of a data object that satisfy a certain criteria, and migrates the identified chunks. For example, the system may determine that a certain number of chunks of a file have not been modified or called by a file system in a certain time period, and migrate these chunks to secondary storage. The system then maintains the other chunks of the file in primary storage. Further details regarding chunks and chunk-based storage may be found in U.S. Patent Application No. 61/180,791, entitled BLOCK-LEVEL SINGLE INSTANCING, filed May 22, 2009.
- In some examples, the system leverages the block-based or chunk-based data migration in order to restore portions of data objects without restoring entire data objects. For example, the system can restore one or more blocks of a file, present the data contained by the blocks, receive modifications to the data, and update the blocks, and hence the file.
- The system will now be described with respect to various examples. The following description provides specific details for a thorough understanding of, and enabling description for, these examples of the system. However, one skilled in the art will understand that the system may be practiced without these details. In other instances, well-known structures and functions have not been shown or described in detail to avoid unnecessarily obscuring the description of the examples of the system.
- The terminology used in the description presented below is intended to be interpreted in its broadest reasonable manner, even though it is being used in conjunction with a detailed description of certain specific examples of the system. Certain terms may even be emphasized below; however, any terminology intended to be interpreted in any restricted manner will be overtly and specifically defined as such in this Detailed Description section.
- Referring to
FIG. 1 , a block diagram illustrating components of a data stream utilized by a suitable data storage and recovery system, such as a system that performs block-based and/or chunk-based data migration, is shown. Thestream 110 may include aclient 111, amedia agent 112, and asecondary storage device 113. For example, in storage operations, the system may store, receive and/or prepare data, such as blocks or chunks, to be stored, copied or backed up at a server orclient 111. The system may then transfer the data to be stored tomedia agent 112, which may then refer to storage policies, schedule policies, and/retention policies (and other policies) to choose asecondary storage device 113. Themedia agent 112 may include or be associated with an intermediate component, to be discussed herein. - The
secondary storage device 113 receives the data from themedia agent 112 and stores the data as a secondary copy, such as a backup copy. Secondary storage devices may be magnetic tapes, optical disks, USB and other similar media, disk and tape drives, and so on. Of course, the system may employ other configurations of stream components not shown in the Figure. - Referring to
FIG. 2 , a block diagram illustrating an example of a data storage andrecovery system 200 is shown. Data storage systems may contain some or all of the following components, depending on the needs of the system.FIG. 2 and the following discussion provide a brief, general description of a suitable computing environment in which the system can be implemented. Although not required, aspects of the system are described in the general context of computer-executable instructions, such as routines executed by a general-purpose computer, e.g., a server computer, wireless device or personal computer. Those skilled in the relevant art will appreciate that the system can be practiced with other communications, data processing, or computer system configurations, including: Internet appliances, network PCs, mini-computers, mainframe computers, and the like. Indeed, the terms “computer,” “host,” and “host computer” are generally used interchangeably herein, and refer to any of the above devices and systems, as well as any data processor. - Aspects of the system can be embodied in a special purpose computer or data processor that is specifically programmed, configured, or constructed to perform one or more of the computer-executable instructions explained in detail herein. Aspects of the system can also be practiced in distributed computing environments where tasks or modules are performed by remote processing devices, which are linked through a communications network, such as a Local Area Network (LAN), Wide Area Network (WAN), Storage Area Network (SAN), Fibre Channel, or the Internet. In a distributed computing environment, program modules may be located in both local and remote memory storage devices.
- Aspects of the system may be stored or distributed on computer-readable media, including tangible storage media, such as magnetically or optically readable computer discs, hard-wired or preprogrammed chips (e.g., EEPROM semiconductor chips), nanotechnology memory, biological memory, or other data storage media. Indeed, computer implemented instructions, data structures, screen displays, and other data under aspects of the system may be distributed over the Internet or over other networks (including wireless networks), on a propagated signal on a propagation medium (e.g., an electromagnetic wave(s), a sound wave, etc.) over a period of time, or they may be provided on any analog or digital network (packet switched, circuit switched, or other scheme). Those skilled in the relevant art will recognize that portions of the system reside on a server computer, while corresponding portions reside on a client computer, and thus, while certain hardware platforms are described herein, aspects of the system are equally applicable to nodes on a network.
- For example, the
data storage system 200 contains astorage manager 210, one ormore clients 111, one ormore media agents 112, and one ormore storage devices 113.Storage manager 210controls media agents 112, which may be responsible for transferring data tostorage devices 113.Storage manager 210 includes ajobs agent 211, amanagement agent 212, adatabase 213, and/or aninterface module 214.Storage manager 210 communicates with client(s) 111. One ormore clients 111 may access data to be stored by the system fromdatabase 222 via adata agent 221. The system usesmedia agents 112, which containdatabases 231, to transfer and store data intostorage devices 113.Client databases 222 may contain data files and other information, while media agent databases may contain indices and other data structures that store the data at secondary storage devices, for example. - The data storage and recovery system may include software and/or hardware components and modules used in data storage operations. The components may be storage resources that function to copy data during storage operations. The components may perform other storage operations (or storage management operations) other that operations used in data stores. For example, some resources may create, store, retrieve, and/or migrate primary or secondary data copies of data. Additionally, some resources may create indices and other tables relied upon by the data storage system and other data recovery systems. The secondary copies may include snapshot copies and associated indices, but may also include other backup copies such as HSM copies, archive copies, auxiliary copies, and so on. The resources may also perform storage management functions that may communicate information to higher level components, such as global management resources.
- In some examples, the system performs storage operations based on storage policies, as mentioned above. For example, a storage policy includes a set of preferences or other criteria to be considered during storage operations. The storage policy may determine or define a storage location and/or set of preferences about how the system transfers data to the location and what processes the system performs on the data before, during, or after the data transfer. In some cases, a storage policy may define a logical bucket in which to transfer, store or copy data from a source to a data store, such as storage media. Storage policies may be stored in
storage manager 210, or may be stored in other resources, such as a global manager, a media agent, and so on. Further details regarding storage management and resources for storage management will now be discussed. - Referring to
FIG. 3 , a block diagram illustrating an example of components of a server used in data storage operations is shown. A server, such asstorage manager 210, may communicate withclients 111 to determine data to be copied to storage media. As described above, thestorage manager 210 may contain ajobs agent 211, amanagement agent 212, adatabase 213, and/or an interface module.Jobs agent 211 may manage and control the scheduling of jobs (such as copying data files) fromclients 111 tomedia agents 112.Management agent 212 may control the overall functionality and processes of the data storage system, or may communicate with global managers.Database 213 or another data structure may store storage policies, schedule policies, retention policies, or other information, such as historical storage statistics, storage trend statistics, and so on. Interface module 215 may interact with a user interface, enabling the system to present information to administrators and receive feedback or other input from the administrators or with other components of the system (such as via APIs). - In some examples, the system performs some or all the operations described herein using an intermediate component, virtual storage device, virtual device driver, virtual disk driver, or other intermediary capable of mounting to a file system and communicating with a storage device. That is, an intermediate component may communicatively reside between a file system and a primary data store that contains data created by the file system and a secondary data store. The intermediate component enables flexibility during data restoration, enabling a file system to indirectly access a secondary copy of data in order to identify information associated with data stored by the secondary copy, among other benefits.
- Referring to
FIG. 4 , a block diagram illustrating a system for performing portion-based data migration is shown. The system components include a data creation and/ormodification component 410, anintermediate component 420, and adata storage component 430. The restorecomponent 410 may include aclient portion 415, such as a client portion that receives input from users. Afile system 417, as discussed herein, may organize and provide data to applications, user interfaces, and so on to the user, among other things. The file system creates, updates, modifies, and/or removes data from a data store, based on input from users. Thefile system 417 may store the created data in one or more data stores, such as alocal database 418 that provides primary storage. For example, thedatabase 418 may be a hard drive or hard disk that stores data produced by the file system as primary copies or production copies of the data. The system components may also include an intermediate component 420 (further described herein), such as a virtual disk driver. Theintermediate component 420 communicates with adisk driver 435 and mounteddisk 437, which together may act as thedata storage component 430. Additionally, theintermediate component 420 may be located between thefile system 417 anddatabase 418. The data storage component provides secondary storage, and may store secondary copies of data generated by thefile system 417, such as secondary copies of primary copies stored indatabase 418. - Referring to
FIG. 5 , a block diagram illustrating theintermediate component 420 ofFIG. 4 is shown. Theintermediate component 420 includes a restoremodule 510 that may contain itsown file system 515. The restore module 510 (or component, sub-system, and so on), may communicate with a file system, such as thefile system 417. Further details with respect the functionality of the restoremodule 510 is described herein. - The
intermediate component 420 may also include astorage device module 520 that communicates with storage devices, such asdisk driver 435 and disk 437 (or other fixed or removable media). Thestorage device module 520 may include anindex 525 or allocation table that identifies available media for data storage, contains information associated with data stored via theintermediate component 420, and so on. - The
intermediate component 420 may also include a cache 530 (or, a cache module or interface that communicates with an external cache), and/or other agents ormodules 540, such as modules that index files, classify files, manage files or information, and so on. - Block-level migration, or block-based data migration, involves migrating disk blocks from a primary data store (e.g., a disk partition) to secondary media. Using block-level migration, a data storage system transfers blocks on a disk partition that have not been recently accessed to secondary storage, freeing up space on the disk. In order to expand the database, the system moves data from the database to other locations, such as other databases or storage locations. Typically, such expansion requires knowledge of the database, such as the database application, the database schema, and so on. However, using block-level migration, the system can expand or extend a database without any knowledge of the applications or schema of the database, providing for transparent migration and/or restoration of data from one storage location to another. This can be helpful when migrating data from virtual machines that contain large files, (e.g., large files created by applications such as Vmware, Microsoft Virtual Server, and so on). The system may implement block-level migration processes as software device drivers, but may also implement block-level migration in disk hardware.
- As described herein, the system can transfer or migrate certain blocks of a data object from one data store to another, such as from primary storage that contains a primary copy of the data object to secondary storage that contains or will contain a secondary copy of the primary copy of the data object. Referring to
FIGS. 6A-6B , a schematic diagram illustrating contents of two data stores before and after a block-based data migration is shown. InFIG. 6A , afirst data store 610 contains primary copies (i.e., production copies) of two data objects, afirst data object 620 and asecond data object 630. The first data object comprises blocks A and A1, where blocks A are blocks that satisfy or meet certain storage criteria (such as blocks that have not been modified since creation or not been modified within a certain period of time) and blocks A′ are blocks that do not meet the criteria (such as blocks that have been modified within the certain time period). The second data object comprises blocks B and B′, where blocks B satisfy the criteria and blocks B′ do not meet the criteria. -
FIG. 6B depicts thefirst data store 610 after a block-based data migration of the twodata objects first data store 610 to asecond data store 640, such assecondary storage first data store 610. - The system can perform file system data migration at a block level, unlike previous systems that only migrate data at the file level (that is, they have a file-level granularity). By tracking migrated blocks, the system can also restore data at the block level, which may avoid cost and time problems associated with restoring data at the file level or may assist in defragmenting a storage device. Further details regarding the block-level restoration of data is be discussed herein.
- Referring to
FIG. 7 , a flow diagram illustrating a routine 700 for performing block-level data migration is shown. Instep 710, the system identifies data blocks within a data store that satisfy a certain criteria. The system may track data blocks and access the blocks via APIs. The data store may be a database associated with a file system, a SQL database, a Microsoft Exchange mailbox, and so on. The system may compare some or all of the blocks (or, information associated with the blocks) of the data store with predetermined criteria. The predetermined criteria may be time-based criteria within a storage policy or data retention policy. - In some examples, the system identifies blocks set to be “aged off” from the data store. That is, the system identifies blocks created, changed, or last modified before a certain date and time. For example, the system may review a data store for all data blocks that satisfy a criterion or criteria. The data store may be an electronic mailbox or personal folders (.pst) file for a Microsoft Exchange user, and the criterion may define, for example, all blocks or emails last modified or changed thirty days ago or earlier. The system compares information associated with the blocks, such as metadata associated with the blocks, to the criteria, and identifies all blocks that satisfy the criteria. For example, the system identifies all blocks in the .pst file not modified within the past thirty days. The identified blocks may include all the blocks for some emails and/or a portion of the blocks for other emails. That is, for a given email (or data object), a first portion of the blocks that include the email may satisfy the criteria, while a second portion of the blocks that include the same email may not satisfy the criteria. In other words, a file or a data object can be divided into parts or portions, and only some of the parts or portions change.
- To determine which blocks have changed, and when, the system can monitor the activity of the file system via the
intermediate component 420, (e.g., the virtual device driver). The system may store a data structure, such as a bitmap, table, log, and so on within thecache 530 or other memory of theintermediate component 420, and update the bitmap whenever the file system calls thedatabase 418 to access and update or change data blocks within thedatabase 418. Theintermediate component 420 traps the command to the disk driver, where that command identifies certain blocks on a disk for access or modifications, and writes to the bitmap the changed blocks and the time of the change. The bitmap may include information such as an identification of changed blocks and a date and a time the blocks were changed. The bitmap, which may be a table, data structure, or group of pointers, such as a snapshot, may also include other information, such as information that maps file names to blocks, information that maps chunks to blocks and/or file names, and so on. Table 1 provides entry information for a bitmap tracking the activity of a file system with the “/users” directory: -
TABLE 1 Blocks Date and Time Modified /users/blocks1-100 09.08.2008 @14:30 /users/blocks101-105 09.04.2008 @12:23 /users2/blocks106-110 09.04.2008 @11:34 /users3/blocks110-1000 08.05.2008 @10:34 - Thus, if a storage policy identified the time 08.30.2008 @ 12:00 as a threshold time criteria, where data modified after the time is to be retained, the system would identify, in
step 710, blocks110-1000 as having satisfied the criteria. Thus, the system, via theintermediate component 420, can monitor what blocks are requested by a file system, and act accordingly, as described herein. - In
step 720, the system transfers data within the identified blocks from the data store to a media agent, to be stored in a different data store. The system may perform some or all of the processes described with respect toFIGS. 1-3 when transferring the data to the media agent. For example, before transferring data, the system may review a storage policy as described herein to select a media agent, such asmedia agent 112, based on instructions within the storage policy. Instep 725, the system optionally updates an allocation table, such as a file allocation table (FAT) for a file system associated with the data store, to indicate the data blocks that no longer contain data and are now free to receive and store data from the file system. - In
step 730, via the media agent, the system stores data from the blocks to a different data store. In some cases, the system, via the media agent, stores the data from the blocks to a secondary storage device, such as a magnetic tape or optical disk. For example, the system may store the data from the blocks in secondary copies of the data store, such as a backup copy, an archive copy, and so on. In some cases, the system stores the data from the blocks to a storage device located near and/or associated with the data store, such as to a quick recovery volume that facilitates quick restores of data. - The system may create, generate, update, and/or include an allocation table, (such as a table for the data store) that tracks the transferred data and the data that was not transferred. The table may include information identifying the original data blocks for the data, the name of the data object, the location of any transferred data blocks, and so on. For example, Table 2 provides entry information for an example .pst file:
-
TABLE 2 Name of Data Object Location of data Email1 C:/users/blocks1-100 Email2.1 (body of email) C:/users/blocks101-120 Email2.2 (attachment) X:/remov1/blocks1-250 Email3 X:/remov2/blocks300-500 - In the above example, the data for “Email2” is stored in two locations, a local data store (C:/) and an off-site data store (X:/). The system maintains the body of the email, recently modified or accessed, at a location within a data store associated with a file system, “C:/users/blocks101-120.” The system stores the attachment, not recently modified or accessed, in a separate data store, “X:/remov1/blocks1-250.” Of course, the table may include other information, fields, or entries not shown. For example, when the system stored data to tape, the table may include tape identification information, tape offset information, and so on.
- Chunked file migration, or chunk-based data migration, involves splitting a data object into two or more portions of the data object, creating an index that tracks the portions, and storing the data object to secondary storage via the two or more portions. Among other things, the chunk-based migration provides for fast and efficient storage of a data object. Additionally, chunk-based migration facilitates fast and efficient recall of a data object, such as the large files described herein. For example, if a user modifies a migrated file, chunk-based migration enables a data restore component to only retrieve from, and migrate back to, secondary storage the chunk containing the modified portion of the file, and not the entire file. In some cases, chunk-based migration may collaborate with components that provide file format and/or database schema information in order to facilitate data recovery.
- As described above, in some examples the system migrates chunks of data (sets of blocks) that comprise a data object from one data store to another. Referring to
FIG. 8 , a block diagram illustrating asystem 800 for providing chunk-based data migration and/or restoration is shown. Thesystem 800 includes afile system 810, acallback layer 820, which interacts with the file system, and adevice driver 830, which reads from and writes data to adata store 840 such as removable media including magnetic tapes, optical disks, and so on. Further details with respect to thecallback layer 820 will be described herein. - As described above, the system migrates data via one or more chunks, such as sets of blocks. A data object, such as a file, may comprise two or more chunks. A chunk may be a logical division of a data object. For example, a .pst file may include two or more chucks: a first chunk that stores data associated with an index of a user's mailbox, and one or more chunks that stores email, attachments, and so on within the user's mailbox. A chunk is a proper subset of all the blocks comprising a file. That is, for a file consisting of n blocks, the largest chunk of the file comprises at most n−1 blocks.
- The
system 800 may include achunking component 815 that divides data objects, such as files, into chunks. Thechunking component 815 may receive files to be stored indatabase 418, divide the files into two or more chunks, and store the files as two or more chunks indatabase 418. Thechunking component 815 may update an index that associated information associated with files with the chunks of the file, the data blocks of the chunks, and so on. - The
chunking component 815 may perform different processes when determining how to divide a data object. For example, thechunking component 815 may include indexing, header, and other identifying information or metadata in a first chunk, and include the payload in other chunks. Thechunking component 815 may follow a rules-based process when dividing a data object. The rules may define a minimum or maximum data size for a chunk, a time of creation for data within a chunk, a type of data within a chunk, and so on. - For example, the
chunking component 815 may divide a user mailbox (such as a .pst file) into a number of chunks, based on various rules that assign emails within the mailbox to chunks based on the metadata associated with the emails. Thechunking component 815 may place an index of the mailbox in a first chunk and the emails in other chunks. Thechunking component 815 may then divide the other chunks based on dates of creation, deletion or reception of the emails, size of the emails, sender of the emails, type of emails, and so on. Thus, as an example, the chunking component may divide a mailbox as follows: -
User1/Chunk1 Index User1/Chunk2 Sent emails User1/Chunk3 Received emails User1/Chunk4 Deleted emails User1/Chunk5 All Attachments.
Of course, other divisions are possible. Chunks may not necessarily fall within logical divisions. For example, the chunking component may divide a data object based on information or instructions not associated with the data object, such as information about data storage resources, information about a target secondary storage device, historical information about previous divisions, and so on. - The system may perform chunking at various times or in different locations of a data storage system. For example, although
FIG. 8 shows thechunking component 815 atfile system 810, the system may locate the chunking component at thedevice driver 830, at an intermediate component, or other locations. In some cases, the system may utilize thechunking component 815 to divide data already in secondary storage into chunks. For example, a data storage system may retrieve data objects under management that were transferred to secondary storage using file-based data migration, divide the data objects into two or more chunks, and migrate the data objects based to storage using the chunk-based data migration discussed herein. Thus, future restoration of the data objects may be faster and easier because the data objects are divided into chunks. - Referring to
FIG. 9 , a flow diagram illustrating a routine 900 for performing chunk-level data migration is shown. Instep 910, the system identifies chunks of data blocks within a data store that satisfy one or more criteria. The data store may store large files (>50 MB), such as databases associated with a file system, SQL databases, Microsoft Exchange mailboxes, virtual machine files, and so on. The system may compare some or all of the chunks (or, information associated with the chunks) of the data store with predetermined and/or dynamic criteria. The predetermined criteria may be time-based criteria within a storage policy or data retention policy. The system may review an index with thechunking component 815 when comparing the chunks with applicable criteria. - In
step 920, the system transfers data within the identified chunks from the data store to a media agent, to be stored in a different data store. The system may perform some or all of the processes described with respect toFIGS. 1-3 when transferring the data to the media agent. For example, the system may review a storage policy assigned to the data store and select a media agent based on instructions within the storage policy. Instep 925, the system optionally updates an allocation table, such as a file allocation table (FAT) for a file system associated with the data store, to indicate the data blocks that no longer contain data and are now free to receive and store data from the file system. - In some examples, the system monitors the transfer of data from the file system to the data store via the
callback layer 820. Thecallback layer 820 may be a layer, or additional file system, that resides on top of thefile system 810. Theintermediate layer 820 may intercept data requests from thefile system 810, in order to identify, track and/or monitor the chunks requested by thefile system 810 and store information associated with these requests in a data structure, such as a bitmap similar to the one shown in Table 1. Thus, theintermediate layer 820 stores information identifying when chunks are accessed by tracking calls from thefile system 810 to thedata store 840. For example, Table 3 provides entry information for a bitmap tracking calls to a data store: -
TABLE 3 Chunk of File1 Access Time File1.1 09.05.2008 @12:00 File1.2 09.05.2008 @12:30 File1.3 09.05.2008 @13:30 File1.4 06.04.2008 @12:30 - In this example, the
file system 810 creates a data object named “File1,” using the chunking component to divide the file into four chunks: “File1.1,” “File1.2,” “File1.3,” and “File1.4.” Thefile system 810 stores the four chunks todata store 840 on 06.04.2008. According to the table, the file system has not accessed File1.4 since its creation, and most recently accessed the other chunks on Sep. 5, 2008. Of course, Table 3 may include other or different information, such as information identifying a location of the chunks, information identifying the type of media storing the chunks, information identifying the blocks within the chunk, and/or other information or metadata. - In
step 930, via the media agent, the system stores the data from the chunks to a different data store. In some cases, the system, via the media agent, stores the data to a secondary storage device, such as a magnetic tape or optical disk. For example, the system may store the data in secondary copies of the data store, such as a backup copy, and archive copy, and so on. In some cases, the system stores the data to a storage device located near and/or associated with the data store, such as to a quick recovery volume. - The system, using the block-based or chunk-based data migration processes described herein, is able to restore portions of files instead of entire files, such as individual blocks or chunks that comprise portions of the files. Referring to
FIG. 10 , a flow diagram illustrating a routine 1000 for block-based or chunk-based data restoration and modification is shown. Instep 1010, the system, via a restore or data recovery component, receives a request to modify a file located in a data store. For example, a user submits a request to a file system to provide an old copy of a large Powerpoint presentation so the user can modify a picture located on slide 5 of 300 of the presentation. For example, thedata recovery component 410 works with thefile system 417 and thedata store 430. - In
step 1020, the system identifies one or more blocks or one or more chunks associated with the request. For example, the system looks to a table similar to Table 2, and identifies blocks associated with page 5 of the presentation and blocks associated with an table of contents of the presentation. - In
step 1030, the system retrieves the identified blocks or chunks and presents them to the user. For example, the system only retrieves page 5 and table of contents of the presentation and presents the pages to the user. - In
step 1040, the system, via the file system, modifies the retrieved blocks or chunks via the file system. For example, the user updates the Powerpoint presentation to include a different picture. Instep 1050, the system transfers data associated with the modified blocks or chunks to the data store. For example, the system transfers the modified page 5 to the data store. The system may also update a table that tracks access to the data store, such as Table 1 or Table 3. - Thus, the system, leveraging block-based or chunk-based data migration during data storage, restores only portions of data objects required by a file system. Such restoration can be, among other benefits, advantageous over systems that perform file-based restoration, because those systems restore entire files, which can be expensive, time consuming, and so on. Some files, such as .pst files, may contain large amounts of data. File-based restoration can therefore be inconvenient and cumbersome, among other things, especially when a user only requires a small portion of a large file.
- For example, a user submits a request to the system to retrieve an old email stored in a secondary copy on removable media. The system identifies a portion of a .pst file associated with the user that contains a list of old emails, and retrieves the list. That is, the system has knowledge of the chunk that includes the list (e.g., a chunking component may always include the list in a first chunk of a data object), accesses the chunk, and retrieves the list. The other portions (e.g., all the emails with the .pst file), are not retrieved from media. The user selects the desired email from the list. The system, via an index that associates chunks with data (such as an index similar to Table 2), identifies the chunk that contains the email, and retrieves the chunk for presentation to the user. The index may include information about the chunks, information about the data objects (such as file formats, database schemas, application specific information, and so on).
- Thus, the system is able to restore the email without restoring the entire mailbox (.pst file) associated with the user. That is, although an entire data object is in storage, the system is able to retrieve a portion of the entire data object by leveraging the processes described herein.
- From the foregoing, it will be appreciated that specific examples of the data recovery system have been described herein for purposes of illustration, but that various modifications may be made without deviating from the spirit and scope of the system. For example, although files have been described, other types of content such as user settings, application data, emails, and other data objects can be imaged by snapshots. Accordingly, the system is not limited except as by the appended claims.
