Determines the backup medium that you want to use.

Syntax: backup_dev_type = disk|tape|pipe|tape_auto|pipe_auto|tape_box|pipe_box|disk_copy|disk_standby|util_file|util_file_online|stage|stage_copy|stage_standby|rman_prep|rman_util|rman_disk|rman_stage

Default: tape

Possible values:

The directory(-ies) that should be used for the backups/archiving is(are) defined in parameter backup_root_dir (possibly in archive_copy_dir).

The parameters tape_auto and pipe_auto generally have no effect on BRARCHIVE, since that program does not support continuation tapes.

For all tape device types, the drivers defined in the parameter tape_address or tape_address_arch are used for the data transfer (cpio, dd). For the rewind those defined in the parameter tape_address_rew or tape_address_rew_ are used.

The parameter util_file allows you to use other storage media (e.g. optical media), provided the supplier provides corresponding backup programs and a BACKINT interface. In such cases, the SAP utilities can call the external backup program for the physical backup or restore of the corresponding files. If parameter util_file_online is used, the volume of offline redo log files is also drastically reduced during an online backup. See External Backup Programs.

Ask the supplier of the non-SAP backup programs and the interface BACKINT for any additionally required parameters for the backup program call. If necessary, store this information in an appropriately maintained parameter file, which you should also enter in the parameter util_par_file or the command option -r|-parfile of the SAP utilities.
