Abstract: A system and method for generating backups of a protected storage system from protected data in a recovery system including protecting data in the recovery system, the recovery system including a target disk configured to store a replica of the protected storage system from a predetermined time point and a journal including data and metadata of write operations to the protected storage system that occurred after the time point, periodically generating replicas of the protected storage system from the recovery system, and storing the replicas as backups.

Abstract: A system and method for verifying consistency of data in a recovery system, the method including: protecting data in the recovery system, the recovery system includes a target disk configured to store a replica of a protected storage system from before a time window and a journal including data and metadata of write operations to the protected storage system that occurred during the time window; verifying consistency of the replicated data, concurrently with the protecting by: copying data of a selected chunk of the protected storage system at a specified time point, while monitoring write operations to the protected system; generating a replica of the selected chunk in the recovery system from the target disk and the journal, from the specified time point; comparing the copied data of the selected chunk with the replica of the selected chunk and repeating the copying, generating and comparing for a plurality of chunks.
