EFFICIENT DATA REHYDRATION

摘要

A system for an efficient data rehydration comprises a server, one or more reader device managers, a writer device manager, and a verifier. The server is for receiving a restore list comprising a plurality of storage locations and lengths for performing a data rehydration. The one or more reader device managers is for reading a data set indicated by the restore list by reading the plurality of storage locations for the lengths from one or more storage nodes. The plurality of storage locations and lengths indicate chunks from a client system stored as part of a full or as an incremental backup session on a storage device attached to a storage node. The writer device manager is for transferring the data set to a save node. A verifier is for verifying transfer of the data set.
