ABSTRACT:
Generating backup sets for a specific point in time from backup data stored in a backup storage device is provided. A backup set, in accordance with an illustrative embodiment, is a collection of the files and data that would have been the most recently backed-up version of a computer's files and data at the particular point in time if the backup set had been created at that point in time. In order to generate the backup set, versions of data objects are identified in the backup storage system that have backup timestamps equal to or prior to the designated point in time and that have deactivation times that are after the designated point in time. In addition, a mechanism for deleting versions of data objects based on a retention time and an inactive version limit is provided.
