Backing
Up to a Group of Parallel Data Carriers 
You can use the Database Manager GUI to back up data to a group of parallel data carriers. This maximizes the data throughput. You can use up to 32 tape devices in parallel.
If possible, we recommend that you back up data to a group of parallel data carriers, rather than backing up to a single data carrier with succeeding data carriers. You cannot make log backups in parallel.
We recommend checking the database structures before each complete data backup.
Prerequisites
Multiple backup devices are available. You have created the required backup templates.
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 from other providers (Backups with Backup Tools from Other Providers), then you must state this specifically when defining the backup template.
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 never made a backup copy for a group of parallel data carriers before, you need to do this as described in Backup Template for a Group of Parallel Data Carriers. Select a backup template in the Media for Backup window.
2. Check the details. Make changes if required (Changing Backup Templates).
3.
Start the backup.
If the capacity of the specified parallel data carriers is insufficient for
the backup and you are not using an automatic tape loader, the Backup Wizard
asks you to specify and insert a new data carrier as soon as the previous data
carrier is full (see Backups to Manually
Changed Data Carriers (Succeeding Data Carriers)).
Result
You can check the results of your data backups using the Backup History.
