Can fbackup be used to backup vg00?

You can use fbackup to backup any part of your machine, or the whole machine. So, Yes, it can be used to backup vg00.

The thing that you can NOT do from an fbackup tape is boot from it. If you happened to lose your root drive, you would have to install a base OS, or recover from the recovery CD, and then frecover from your fbackup tape.

This is why ignite is such a nice tool. You can make your make_tape_recovery tape and if need be, boot from it and have your whole VG00 restored and the system back up and running in a fairly short time.

we always make a couple of make_recovery tapes and then a couple of fbackups of vg00 just incase we run into problems. make_recoverys are excellent for recovering the whole system, fbackups are great for covering up fat finger problems after the "rm" command

Hi, if you use make_recovery with the -A option it will back up the entire root volume group. Hope this helps.

Hi Jeff:

There is one very good reason for periodically making an 'fbackup' tape of vg00 in addition to making regular 'make_tape_recovery' tapes.

In the event that you want to reload an individual file, or even a directory of files, and you have an fbackup tape, then recovery of the file(s) will be extremely fast. 'fbackup' writes fast search marks as it copies data to its tape, giving 'frecover' the ability to quickly locate and copy files from tape back to disk.

You can extract individual files from an Ignite "recovery" tape too. However, since the files were written with the 'pax' (a tar-like) utility), there is no ability to quickly search the tape. Finding a file in the middle of the tape is slow to say the least.
