Description
Technical field
The present invention relates to a kind of file backup method, particularly a kind of file backup method according to the suitable stand-by program of file type Dynamic Selection.
Background technology
The definition of backup is meant that a kind of source device from the beginning reads the desire Backup Data, deposits target device in and backs up through desiring Backup Data after the proper process.In general, backup is a kind of means to important data security protecting, also promptly, if come the data of source device to be damaged, as long as before corrupted data, promptly carry out backup, just can utilize the data that are stored in the target device to reduce the data in the source device.
Backup tool divides as two big types basically at present: file backup instrument and volume backup tool; The file backup instrument is used to back up specified specific file of user and catalogue;, backs up the file system operation interface after reading through an archival backup; File backup instrument biggest advantage is to select the dirigibility of backup file high, and the user gets the file that a part of only handling a volume need back up and get final product, rolls up backup tool and then be the reading of data on the source device always; Directly the whole row that involves in is backed up through a volume stand-by program; It is comparatively convenient that advantage is concerning big data backup, but because selectivity is so not high, be used in the backup of operating system mostly.
Though the selectivity of file backup instrument is strong; Can back-up specific file and catalogue; But when (for example: in the time of sparse file (Sparse File)) running into special file type; If when selecting for use the file backup instrument to back up, can to the central processing unit of system (Central Processing Unit, CPU), internal memory and hard drive space cause the great wasting of resources.With the sparse file is example, and the most content of its content is zero data, has only the sub-fraction space to comprise the data of non-zero; In other words, suppose one 5,000 hundred million byte (500Giga-byte, 500GB) sparse file of data volume; The actual valid data that possibly have only 2 gigabit hytes (2GB); If when backing up with generic-document back-up instrument, must first data volume all read out 500GB, write target device again.
Therefore, how can be through a kind of method or means, can let the file backup instrument be able to more efficient some special file carried out stand-by program, be the target that relevant at present manufacturer makes great efforts exploitation.
Summary of the invention
Can't handle special file efficiently in order to solve the current file backup tool; The object of the present invention is to provide a kind of backup method; Let the file of specific type use the volume treatment technology to back up; Other file still keeps the backup mode that uses the file backup tool technique, this measure can the advantage of the original high flexibility of document retaining backup tool outside, also can save a large amount of central processing units (Central Processing Unit; CPU), the resource of internal memory and hard drive space, improve the operational efficiency of backup tool.
Therefore backup method of the present invention can be applied in the backup of long-range (network) because of possessing the low-resource demand, can be considered a kind of high in the clouds redundancy technique of novelty.
Backup method of the present invention; Be to carry out the backup of file according to the suitable stand-by program of file type Dynamic Selection; This document backup method comes source device to obtain a listed files from one earlier; Choose in regular turn according to the files classes table and to treat backup file, and obtain this essential information of treating backup file and specific information respectively; According to this essential information and this specific information, judge in regular turn that again this that obtained treat whether backup file is a special file.
When this treats that backup file is this special file, read the data content that this treats backup file through a volume operation-interface, and, this data content of treating backup file is backed up to a target device with a volume stand-by program according to this specific information.When this treats non-this special file of backup file, read the data content that this treats backup file through a file operation interface, and, this data content of treating backup file is backed up to this target device with an archival backup according to this essential information.
Therefore; Through above-mentioned method; The backup method of this method utilizes the preceding type of judging file earlier of backup, determines whether still being that archival backup backs up through the volume stand-by program; So can avoid because of special file cause central processing unit (Central Processing Unit, CPU), internal memory and hard drive space cause great resource consumption.
Describe the present invention below in conjunction with accompanying drawing and specific embodiment, but not as to qualification of the present invention.
