Title: IMPROVING BACKUP PERFORMANCE AFTER BACKUP FAILURE
Abstract:
Disclosed herein are methods, systems, and processes to improve backup performance after backup failure. It is determined whether a backup operation is successful. In response to a determination that the backup operation was unsuccessful, backup metadata associated with the backup operation is replaced with snapshot metadata associated with a snapshot that is taken at a first point in time that is prior to initiation of the backup operation. A rolled-back snapshot that permits another backup operation to be performed at a second point in time based on the snapshot metadata is then generated.
