Validating replication copy consistency using a hash function in a storage system

摘要

Described embodiments provide systems and methods for operating a storage system. One or more data replicas of production data of the storage system are generated. For each of the one or more data replicas, an associated hash value is generated. The one or more data replicas are stored in a replica storage of the storage system, and the associated hash values are stored as journal data associated with the respective data replica. Each data replica is verified based upon the hash value retrieved from the journal data.
