FILE |
|
Do not create backups on data carriers of the FILE type that are located on the same hard disk as the volumes of the database. Always back up to a separate hard disk. If your data carriers are located on the same computer as the database, regularly copy the backups to other computers or data carriers using operating system commands. |

You can use autoloaders. Do not use tapes more often than is recommended by the manufacturer. Unix:

PIPE |
|
On Microsoft Windows, the pipes are created by the database kernel. On Unix, the pipes are not created by the database kernel:
Before you carry out a log backup to a pipe without a third-party backup tool or with a third-party backup tool not directly supported by SAP MaxDB, first set the value of the special database parameter EnableLogBackupToPipe to YES. This ensures that the system can overwrite the log entries in the log area that have already been written to the pipe. Note that the system does not check whether the log backup to the pipe was successful. More information: Database Administration, Special Database Parameters |
