To restore a database instance after an error or system failure, you can use the Database Manager GUI to import data and log backups. You can restore the database instance to its last state or to an earlier state.
You can also use the Database Manager GUI to restore indexes and mirrored log volumes.
If the automatic log backup function has been activated before the recovery of the database instance started, this function is not automatically reactivated after the recovery. To reactivate the log backup function, proceed as described under Activating the Automatic Log Backup.
