make_tape recovery ?

[Nabil Boussetta]

is make_tape_recovery sufficient to recover after a system crash?
do you to do something in addition?

[Arunvijai_4]

The make_tape_recovery tool creates a system recovery archive and stores the archive on a local tape. It is capable of creating system recovery tapes for tape devices, with the ability to span multiple tapes. The archive created by make_tape_recovery is specific to the system it was created for and its identity includes the host's name, IP address, networking information, etc. In the event of a root disk failure, the recovery archive can be installed using tape to restore the system.

make_tape_recovery doesn't (necessarily) backup EVERY file on your system. It is designed to get your system to a state where you can then recover your user data etc from a full backup.

First of all see if the system will come back up without restoring.

Did you backup the whole of vg00 when you did the backup? If not, there may be additional work to do.

Although make_tape_recovery can include other VGs, it is primarily intended to recover VG00, the root VG. Once you have your root VG recovered, you can then use your regular backups to recover your other data. Make_tape_recovery has none of the advanced capabilities of even the simplest of the regular backup vehicles and is not intended to be used for anything other than recovery.

Hi,
We normally do make_tape_recovery for OS backup (VG00), depends on your case, if you backup your entire system (os,data, and apps) using make_tape_recovery, it is sufficient to recover back using this methode.

[MarkSyder]

It is not a good idea to use ignite to backup apps and data - that's not what it's designed for. It's only for giving you a bootable system after a crash (which is how I interpret the question that's been asked).

For restoring apps and data you should use something like DataProtector.

Nabil,
yes it's sufficient if you created a make_tape_recovery archive including all VG of your system,
otherwise you should restore the root VG, then recreate the other VGs and restore data in these from backups that hope you did.


But if you have for example 2 VG:
VG00 = root VG
VG01 = Vg for data and applications

Then, if you did a tape in this way:
/opt/ignite/bin/make_tape_recovery -I -A -x inc_entire=VG00 -x inc_entire=VG01
then you can restore ALL your system, including non-system data (VG01)


Have a look to these documentations for further details:

At risk of becoming repetitive, this is not what ignite is designed for. It is designed for operating system ONLY. Non-system data should be backed up with, for example, DataProtector.

i have the following config:

an hp-ux11i machine connected to an EVA3000

the vg00 contains all system config
2 others vg (vg01 and vg02) that contains app data

i run make_tape_recovery with the following options. make_tape_recovery -A ( vg00 is backuped on 0mn Tape)

others vg are backuped by DATAPROTECTOR.

if i restore with make_tape_recovery. could i recover the config of other vg (only config, not data)

[Pete Randall]

Run "make_tape_recovery -a /dev/rmt/_mn -I -v -x inc_entire=vg00" to create your archive. This will ensure that you have everything necessary in vg00. If you don't specify the inc_entire, Ignite backs up just what it considers necessary and this probably won't include the definitions of other VGs.

Hi Nabil ,

To backup your system with ignite-ux make_tape_recovery , you can run :

#/opt/ignite/bin/make_tape_recovery -v -I -x inc_entire=vg00 -a /dev/rmt/0mn

Check if the backup is successful :

# cd /var/opt/ignite/recovery/latest
# cat recovery.log | grep -i successful

And you are safe now , you can recover your system , for any kind of OS failure. This tape is bootable , and can be boot from this tape to restore the system. And all filesystems of vg00 will be restored.
Cheers,
Raj.
