description 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.
