## Backing Up to a Single Data Carrier

You can use the Database Manager GUI to back up data or log entries to a single data carrier.

If possible, we recommend that you back up data to a group of parallel data carriers, rather than backing up the data 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

Only one backup device is available. You have created a backup template for a single data carrier.

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 creating 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 not yet created a backup template, you need to do this now as described in Backup Template for a Single Data Carrier.
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, or activate automatic log backups.
If the capacity of the specified 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 Carrier (Succeeding Data Carrier)).

### Result

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