Technical field
The present invention relates to hard disk failure technical fields.It is more particularly related to which a kind of carry out hard disk using cloud
The method that data are restored.
Background technique
Currently, common hard disk includes mechanical hard disk and solid state hard disk, since mechanical hard disk is easy by temperature, the shadow of vibration
It rings and read-write error occurs, and the intrinsic erasable number limitation of solid state hard disk itself and bad block rate also result in read-write error.Though
Right hard disk has error correcting capability, but it can only correct the less wrong data of number of errors, error correction by itself error correction algorithm
Ability is limited.
In the prior art, when the number of errors of wrong data is too many, hard disk can not carry out error correction by itself error correction algorithm
When, storage control mostly uses RAID (Redundant Array of Independent Disks, the redundancy battle array of independent disk
Column) algorithm corrects mistake, and is restored by reconstruction or format manipulation to hard disc data.If during reconstruction operation
There is mistake in other hard disks in hard disk array, and the data in hard disk will be unable to restore；And format manipulation needs to carry out entirely
The reading data of magnetic track, formats and data write operation twice, for the first time for the data of entire magnetic track (including are passed through RAID
Other data where recovery data and wrong data that algorithm obtains on magnetic track) write-in reservation region, being for the second time will be entire
On magnetic track after the completion of the data writing format of magnetic track, frequent operation is relatively time-consuming, and it is hard for saving for retaining region
The parameter and configuration information of disk carry out that biggish risk can be brought when first time data write operation.The prior art is to improve firmly
