Unless HISTORY OFF is specified, each RESTORE DATABASE operation updates a backup history file called backup.syb. This file records the BACKUP and RESTORE operations that have been performed on a database server. You may want to prevent the RESTORE DATABASE operation from being recorded in backup.syb if the following conditions apply:

RESTORE DATABASE replaces the database that is being restored. If you need incremental backups, use the image format of the BACKUP command and save only the transaction log; however, image backups to tape are not supported.

During the execution of this statement, you can request progress messages. See progress_messages option.

You can also use the Progress connection property to determine how much of the statement has been executed. See Progress connection property.

The following example restores a database from a tape drive. The number of backslashes that are required depends on which database you are connected to when you execute RESTORE DATABASE. The database affects the setting of the escape_character option. It is normally set to On, but is set to Off in utility_db. When connected to any database other than utility_db, the extra backslashes are required.

RESTORE DATABASE 'd:\\dbhome\\mydatabase.db'
FROM '\\\\.\\tape0';
