Backups

[Ricky B. Nino]

Hi,

I just want to make sure that I have a complete set of backup in case of systerm failure.

What I have are...
1) recovery tape (make_recover -Av) 2) FULL File Sytem BAckup

Are these enough to restore a completely exactly the same system I have?

Thanks in advance...

I would make sure that I had the latest version of Ignite/UX and use the make_tape_recovery command. That will get everything in /dev/vg00. Any non-vg00 data should be backed up with
conventional backups like fbackup, cpio, tar, or OmniBack.

Even this is not quite sufficient to get you exactly back to where you were but you will have a running machine. You would still need to remirror the vg00 lvols if you are running Mirror/UX.

That will work except for open database files and databases stored on raw disk.

The oracle backup you'll get off that will be called fuzzy and recovery is not supported off that kind of backup.

make_tape_recovery and its predeccsors use make_sys_image which uses pax. pax can't handle files bigger than 2Gig

Also make_recover is obsolete. You want to use make_tape_recovery

Best strategy btw is to use make_tape_recovery to backup vg00 and fbackup or omniback for the rest of the system.

disk configuration for other volume groups will be preserved in such a strategy.

As stated make_recovery is obsolete.

Use make_tape_recovery
e.g

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

Using other backup products will give you the rest of the information you require. It speed and dependability will depend on the dollars and cents your business is willing to spend and the scale of systems bein used. If you have smallish systems, and can afford a small amount downtime, then using something like 'fbackup' for the rest of your system will suffice.

Guys,

Atleast for now I know that I am within the industry standards.

Thanks for the introduction of 'make_tape_recovery'. I have read the man pages and its quite powerful and friendly. I will make a backup of my system immediately with this command.

Thanks very much...

BTW, any way I would know if such command is becoming obsolete? Does HP have an online message board for cases such as these?

Ricky:

The release notes for a product are probably the best place to keep aware of the changing landscape. For 11.11, by way of example, you would look at:

http://docs.hp.com/hpux/onlinedocs/5187-1841/5187-1841.html

A very valuable general link is the Software site:

http://www.software.hp.com

and:

In the case of Ignite, the announcement of 'make_tape_recovery' appeared in the Ignite release notes for version 3.2 in January 2001.

http://www.software.hp.com/products/IUX/docs/release_note.html

Therein, it was noted that "A new command, "make_tape_recovery" has been added to this release...It is planned for make_tape_recovery to eventually obsolete
make_recovery...make_recovery will still be
functional and will give a note stating that it will be replaced in a later release...".

Regards!
