full backup

Jeff Hagstrom — Fri, 20 Sep 2002 12:01:51 GMT

I need to do a full back up of our system, are there are special commands to use to make sure that I get everything?

Use fbackup to backup your system and make_tape_recovery to make sure you can rebuild (recover) your system in case of a hardware failure.

What kind of system do you have?

What kind of tape drives are available?

What OS is running?

What waws the last patch bundle installed?

What do you want to use to do the backup? tar, cpio, fbackup?

fbackup is actually probably the best bet here. You can run this from within SAM if you like. Go into SAM, then into the Backup / Recovery area define your backup and let it run.

I would also consider installing Ignite/UX to backup your VG00 so that you have a bootable backup tape should VG00 ever get royally fried.

Ignite is loaded and I do have a bootable tape. The machine is a hpk460.

OK, so the machine is a K460, BUT

What kind of tape drives are available?

What OS is running?

What was the last patch bundle installed?

What version of Ignite??

Hi Jeff:

I'd use a current version of Ignite to create a bootable recovery tape of vg00:

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

If you don't have a relatively recent version, or want the latest, get it here:

http://www.software.hp.com/products/IUX/download.html

For your non-vg00 volume groups, I'd use 'fbackup' with one or more graph files to specify the mountpoints that represent your application data. For speed of backup, and for good tape utilzation, I'd make sure to specify a 'config' file for 'fbackup' that looks like:

blocksperrecord 256
records 32
checkpointfreq 1024
readerprocesses 6
maxretries 5
retrylimit 5000000
maxvoluses 200
filesperfsm 2000

Note that the 'readerprocesses' default is two (2), but six (6) are allowed. The higher the number the more concurrent processes read data to deliver to the tape. Too low a number may result in the tape drive falling in and out of streaming mode thereby reducing copy times significantly.

If you want to guarantee that you get everything, do your backups while in single user mode.

and is running ux-11.00 and ignite is b.3.3.116. Patch??

Jeff,

Yes UPGRADE IGNITE, then do a make_tape_recovery and then apply the most recent patch bundle, then another make_tape_recovery, THEN contemplate what kind of backup to perform.

Hi Jeff:

With regard to patch levels, etc., your Ignite version is getting old. The latest Ignite version is 3.7.96.

I'd download this version and 'swinstall' it. This doesn't take long and doesn't require a reboot before you can start using it.

If you are planning to update your patches, I'd use a current SupportPlus Quality Pack (QPK) bundle, but *only* after I had created a current Ignite recovery tape as I suggested in my first post.

Regards!
