Backup and Restore Considerations

If you perform a backup, the database server performs a full checkpoint and flushes all changed pages, including those for fuzzy operations, to the disk. If you perform a restore, the database server reapplies all logical-log records.

Important:
Because the logical log contains records of fuzzy operations not yet written to disk, you must back up the logical logs regularly.
