Embodiment
For making the object, technical solutions and advantages of the present invention clearly understand, hereinafter will be described in detail to embodiments of the invention by reference to the accompanying drawings.It should be noted that, when not conflicting, the embodiment in the application and the feature in embodiment can combination in any mutually.
Fig. 1 is the process flow diagram of the method for backup disk data of the present invention, is applied in the disk array (Raid) with redundancy feature, as shown in Figure 1, comprises:
Step 101: when monitoring computing machine and reaching down state threshold value, according to the utilization factor of pre-recorded computing machine and the one-to-one relationship of each time period, determines the time period corresponding to minimum utilization factor of this computing machine.
Wherein, computing machine down state refers to: the disk system collapse of computing machine.
Illustrate, to have three pieces of disk configuration Raid5, first piece of disk failures, computing machine can normally use, and during second piece of disk failures, computing machine just can thoroughly be paralysed, computing machine down state now, when referring to this second piece of disk failures.It should be noted that be conventional techniques means well-known to those skilled in the art about how whether monitoring computer reaches down state threshold value, do not repeat them here, be not used for limiting the present invention.
Before step 101, the method also comprises: obtain the utilization factor of each time period of computing machine and record the utilization factor of this computing machine and the one-to-one relationship of each time period.And,
In monitoring computer each disk state and record the time point of each disk failures; Wherein Disk State comprises normal or breaks down.
It should be noted that, be conventional techniques means well-known to those skilled in the art about the utilization factor how obtaining computing machine, is not used for limiting the present invention.
Further, when monitoring first piece of disk failures, sending alarm and pointing out replacing first piece of disk.
Further, after having changed first piece of disk, the method has also comprised: utilize Raid function to be the recovery that the new hard disk changed realizes data.
Wherein, determine the time period corresponding to minimum utilization factor of this computing machine, comprising:
