How to take OS backup using make_tape_recovery? How to take Ignite backups of the HP-UX system on to a Tape drive?

First identify if your system has a tape drive in place.

ioscan -fnC tape

or

ioscan -kfnC tape

Say the tape device is /dev/rmt/0m and has the no-rewind device file for the same tape as /dev/rmt/0mn

To make the Tape archive of the system use the no rewind device that is /dev/rmt/0mn.

Load the tape media in the tape device.

Confirm that the media is loaded and in case needed rewind the tape to the home position.

mt -t /dev/rmt/0mn status

To rewind to the original tape home position you can do

mt -t /dev/rmt/0mn rewind

or

in short

mt -t /dev/rmt/0mn rew

Confirm the tape is positioned

mt -t /dev/rmt/0mn status

To make a Tape archive backup you can use the command as

make_tape_recovery -Av

This automatically takes backup to the default tape drive configured on the system.

make_tape_recovery -v -a /dev/rmt/0mn -x include_entire=vg00 -x exclude=/var/adm/crash

The above command takes backup of the system into tape drive /dev/rmt/0mn and includes entire VG vg00 (which is included in Ignite backup by default) in -v (verbose mode) and excludes the Directory /var/adm/crash.

To include the other VGs apart from the rootvg vg00, the command becomes like this.

make_tape_recovery -v -a /dev/rmt/0mn -x inc_entire=vg00 -x inc_entire=vg02 -x exclude=/var/adm/crash

The above command additionally takes the vg02 data also in the Ignite tape backup.
