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

You can use the Database Manager GUI to back up data to a group of parallel backup media. This maximizes the data throughput. You can use up to 32 tape devices in parallel.

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

We recommend checking the database structures before each complete data backup.

Prerequisite

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 with Automatic Tape Loaders), or with the help of external backup tools (Backups with Backup Tools from Other Providers), then you must state this specifically when defining the media.

Under normal circumstances, you should back up database instances in the ONLINE operational state.

You can also back up database instances in the ADMIN operational 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 details. Change them if required (Changing Backup Media).

       3.      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 to Manually Changed Media (Succeeding Media)).

Result

You can check the results of your data backups using the Backup History.
