Restoring the <SAPSID> Backup from a
Device
...
Use
Use this procedure if the msdb database is not up to date and you therefore cannot perform a normal restore using the backup history of msdb tables.
Depending on the overall restore procedure that has to be carried out, you may have to repeat the procedure many times. It is very important that the backup tapes are labeled correctly while the backup was performed, and the tapes are inserted into the tape device during this restore procedure in the correct sequence so that the restore operation will be successful.
Process Flow
1. If your database fails, try to back up the current state of the transaction log.
2. You restore the most recent full backup without recovering the database.
You use the following restore option:
Leave the database non-operational, and do not roll back the uncommitted transactions. Additional transaction logs can be restored.
3. If a differential backup exists, you restore the most recent differential backup without recovering the database. You use the following restore option:
Leave the database non-operational, and do not roll back the uncommitted transactions. Additional transaction logs can be restored.
4. You restore all transaction log backups that you created since the last full backup or differential backup (if available) without recovering the database. You restore the log backups in a sequence beginning with the eldest log backup except the last active transaction log (if available).
¡ If the last active transaction log is available, set the following restore option:
Leave the database non-operational, and do not roll back the uncommitted transactions. Additional transaction logs can be restored.
¡ If the last active transaction log backup is not available, set the following restore option:
Leave the database ready to use by rolling back the uncommitted transactions. Additional transaction logs cannot be restored.
5. If you were able to back up the last active transaction log backup, set the restore option:
Leave the database ready to use by rolling back the uncommitted transactions. Additional transaction logs cannot be restored.
Restore the active transaction log.
