Abstract: A system and method for generating replicas of a file of a protected storage system from protected data in a recovery system. The method including protecting data in a recovery system including a target disk configured to store a replica of the protected storage system from a 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, obtaining a request to restore a file and an indication of a specified time point from which the file should be restored, generating a replica of a table of content of a file system of the protected storage system from the journal and the target disk, extracting location of the file from the table of content, and generating a replica of the file from the journal and the target disk, using the extracted file location.

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.

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 protecting data in a protected storage system. A replication of the protected storage system at a predetermined time point is stored in an object-based storage in replicated content objects of a target disk. Information related to a write operation in the protected storage system is obtained, the information including: data stored on the protected storage system and metadata related to the stored data. A journal is maintained by: including a copy of the stored data in a content entry in one or more journal content objects, including at least some of the metadata in a metadata entry in one or more metadata objects, storing the journal content objects and metadata objects in the object-based storage, and associating the metadata entry with the content entry. The data received before a predetermined time window is periodically moved from the journal to the target disk.
