Recoveries using backup copies of the database

Tivoli® Storage Manager provides programs to recover the database, should a catastrophic failure occur.

These programs restore the database from the latest available full backup copy, apply all incremental backups that apply, and use the recovery log to apply any changes made to the database since the last backup was created.

If you restore the database to its most current state, Tivoli Storage Manager should automatically synchronizes the database and storage volumes.

If you restore the database to a specific point in time, you must audit all storage volumes to check for and resolve any inconsistencies between the information in the database and the actual information on the storage volumes. Depending on the number of storage volumes and the amount of activity that occurred after the database backup that you restored, the audit might require a significant amount of time.

To perform a database recovery, you should have the following information, preferably stored at a different location:

Back up volumes of the database
Copy storage pool volumes
Server options file
Storage volume history
Device configuration history
Output from commands that provide details of the database and recovery log setup

See the Tivoli Storage Manager information for details about recovering data.
