Zusammenfassung: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.
