  • Method and Device for Differential Data Backup
    Publication number: 20170269847
    Abstract: A method for a source storage device replicating data to a backup storage device, where the source storage device identifies a current fingerprint set based on an identifier of a current backup period. Each of the plurality of fingerprint sets corresponds to a backup period. The current fingerprint set includes one or more fingerprints and identifies one or more data blocks respectively. The one or more data blocks are received by the source storage device between an end moment of a previous backup period and a start moment of the current backup period. Further, the source storage device obtains the one or more data block and sends them the backup storage device. Therefore, data backup efficiency can be improved.
