Backing up a table space or table space partition

Use the Backup page of the backup notebook to create a backup image that can be used to restore the table space or table space partition.

Note:

In a partitioned database environment, you back up at the table space partition level.

You can only access this notebook if the database or database partition is enabled for forward recovery (that is, the userexit or logretain configuration parameter, or both, is enabled), and an offline backup copy of the database or database partition has already been taken.
