Procedure documentation Backing Up to a Group of Parallel Backup Media Locate the document in its SAP Library structure

You can use the Backup Wizard to back up data interactively. To maximize the speed of the backup, you can back up data to a group of parallel backup media. You can use up to 32 tape devices to reduce backup times significantly.

Note

If possible, we recommend that you back up data to a group of parallel backup media, rather than backing up the data to a single backup medium with succeeding media. You cannot make log backups in parallel.

Recommendation

Always check the database structure before each complete data backup (see Checking Database Structures).

Prerequisites

There are multiple backup devices available.

You have created the required backup media.
If you want to perform a backup using an automatic tape loader (Backups to Automatic Tape Loader), or with the help of external backup tools(Backups with External Backup Tools), then you must state this specifically when defining the media.

Note

Under normal circumstances, you should backup database instances in the ONLINE operational state.
You can also backup database instances in the ADMINoperational state, but only in exceptional circumstances.

Procedure

Use the Backup Wizard.

       1.      If you have not yet created a group of parallel backup media, do this now as described in Creating a Group of Parallel Backup Media. Select a group of parallel backup media in the window Media for Backup.

       2.      Check the information, and change it, if necessary ( Changing Backup Media).

       3.      Only for database systems up to version 7.3 (inclusive):
If you want to perform a data backup, now choose whether the backup is to be performed for Recovery orMigration.

Recovery : Data backup for restoring the database instance if errors occur
Migration: Data backup with checkpoint; that is, to migrate the database instance
For more information about checkpoints, see the User Manual: SAP DB 7.3.

       4.      Start the backup.
If the capacity of the specified group is not large enough for the backup and you are not using an automatic tape loader, the Backup Wizard asks you to specify and insert a new backup medium as soon as the previous medium has been filled (see Backups with Manually Changed Media).
