Backups with Automatic Tape Loaders (SAP Library - Database Manager GUI: SAP DB 7.4)

Backups with Automatic Tape Loaders

The Database Manager GUI supports automatic tape loaders. Alternatively, you can backup using an external backup tool (Backing Up with External Backup Tools).

If you want to use an automatic tape loader for backups, select Extended when defining the medium (Defining a Single Backup Medium, Defining a Group of Parallel Backup Media or Changing Backup Media) and select the Autoloader option.

On the Microsoft Windows NT/Windows 2000 operating system, this defines the automatic loading of tapes.

If you are using a different operating system, under media definition enter the command the operating system requires for automatic tape loading; to do this, select Extended and enter the operating system command in the OS Command field.

After inserting the tape cartridge in the autoloader, the first tape must be selected manually.
When the end of this tape is reached, the autoloader will then take the next tape available.

For a backup to be successful, you will need to ensure an adequate supply of tapes.

At the end of the backup, the tape device shows the number of tapes written. The tapes should be marked with the backup ID that was displayed and confirmed at the start of the backup.

Note

Before a backup you must check that none of the tapes is write-protected because this will terminate the entire backup process.
