description A system, method, and medium for performing incremental backups of a Microsoft SQL server database. A snapshot of the database is created, and then a map identifying the changed extents is retrieved from the snapshot. The changed extents are then retrieved from the snapshot and stored in a backup storage device. For a restore operation, a full database backup file is written to a storage device and then the changed extents from a stored incremental backup file may be merged with the full backup file. Next, the database server is notified of the reconstructed file and then the reconstructed file is mounted by the database server as a live instance of the database.
