  • Patent number: 11954066
    Abstract: An identification of a new primary snapshot created for a primary storage system is received. A change tracking time window that is at least a portion of a period between a first capture time associated with a previous primary snapshot and a second capture time associated with the new primary snapshot is determined. Entries of a storage log of the primary storage system occurring within the change tracking time window are analyzed to coalesce changes identified in the entries of the storage log occurring within the change tracking time window into a change tracking result set. The change tracking result set is used to identify at least a portion of data changes between the previous primary snapshot and the new primary snapshot to capture in a new backup snapshot stored at a secondary storage system.

  • Patent number: 11886298
    Abstract: An identification of a new primary snapshot created for a primary storage system is received. A threshold time window based on a capture time associated with the new primary snapshot is determined. Entries of a storage log of the primary storage system occurring within the threshold time window are analyzed to identify any objects of the primary storage system that have changed during the threshold time window. Changed objects to capture in a new secondary backup stored at a secondary storage system and corresponding to the new primary snapshot are identified. Metadata of the new primary snapshot and metadata of a previous secondary backup are compared to determine for each of the objects of the primary storage system identified as having changed during the threshold time window whether a change to an object since the previous secondary backup is captured in the new primary snapshot.
