Abstract
To avoid possible data corruption resulting from restoring data to a database from a backup set that is not valid for the database, attempted restore operations are intercepted before they are performed. The backup set is examined to determine whether it was created from the same recovery fork on which the database resides or an descendant of that recovery fork. The backup set is only allowed to be applied to the database if the backup set was created from one of these recovery forks. If not, the backup set is not allowed to be applied to the database.
