Abstract: A system and method for verifying consistency of data in a recovery system may include 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. The verification may include storing in the journal a first bit string that uniquely identifies a selected chunk of the protected storage system from a specified time point, and when the specified time point goes past the limit of the time window, comparing the first bit string with a second bit string that uniquely identifies a corresponding chunk that is stored in the target disk.

Abstract: A system and method for generating incremental backups for a protected storage system may include storing in a journal data and metadata related to modification of data in the protected storage system and marking, in a memory changed block tracking (CBT) object, storage units that were modified on the protected storage system. A system and method may store a copy of a CBT object in a storage system to produce a stored CBT object. A stored CBT object may be loaded into memory to produce a memory CBT object. A CBT object may be used to identify storage units to be included in an incremental backup.
