Method and system for recovering data from storage systems

Abstract:

A method and system for recovering data from a storage system is disclosed. The method includes predicting, by a fault tolerance device, a fault within the storage system comprising one or more disk array enclosures, wherein each of the one or more disk array enclosures comprise a plurality of disks. The method further includes identifying, by the fault tolerance device, a data block going to be affected by occurrence of the predicted fault, wherein the data block is identified within a first disk in the plurality of disks. The method includes extracting, by the fault tolerance device, data stored in the data block before occurrence of the predicted fault. The method further includes transferring, by the fault tolerance device, the data extracted from the data block to a second disk not going to be affected by occurrence of the predicted fault.
