Abstract:
A system and method for performing a granular restore operation of a database from a differential backup of the database. A bitmask is created during a differential backup and stored with the differential backup file. When a user requests a granular restore operation, views of how the database existed at different points of time may be presented to the user. The objects the user wishes to restore may be selected from one of the views. Next, the bitmask may be read to determine if the objects should be retrieved from the differential backup file or a full backup file. Finally, the objects may be restored to the database from the proper file.
