Backup device configuration

[Former Member]

Hi Experts,

I have read few posts , and they are quiet useful..What i need to know more about is, I need to give the Path for my External Tape Drive.

I have defined the type as Tape.

1. backup device type

2. [tape | tape_auto | tape_box | pipe | pipe_auto | pipe_box | disk

3. | disk_copy | disk_standby | stage | stage_copy | stage_standby

4. | util_file | util_file_online | rman_util | rman_disk | rman_stage

5. | rman_prep]

6. default: tape

backup_dev_type = tape

I have to define the Path how can i tell the system to backup to Extrenal tape drive.

1. backup root directory (<path_name_list>)

2. default: $SAPDATA_HOME/sapbackup

backup_root_dir = $SAPDATA_HOME/sapbackup

Thanks

Adnan,

The address of the external tape drive is in the init.sap parameters tape_address and tape_address_rew. The first parameter specifies the device file name of the tape-drive in no-rewind mode, the second is the device file with automatic rewind at end-of-file (used to write the last file of the backup to the tape volume). The default values provided in the template are often the correct ones for the actual server.

If you wish to use separate tape drives for database backups and archive log backups, then you should also configure the parameters tape_address_arch and tape_address_arch_rew. These will then be used only for the BRARCHIVE backups.

Other parameters are also involved e.g. to specify the tape size, the compression mode and others. For these I urge you to download the SAP Database Guide for Oracle, which you can find at [|]. Every init.sap parameter is explained in detail there.

backup_root_dir only applies to disk backups; with tape backups, only the control information (logs) is written there.

Regards,

Mark
