Make_recovery

[TANHM]

Hi all masters :-)

The following is my question:

If I make_recovery (onto a DDS tape drive) on a HP-UX 11.11, can i restore back the data (not all vg00) back onto the system???? As my current setting is all file systems are goup into vg00.....therefore i thinking of whether i can backup without using fbackup or tar (By using make_recovery). (I know that make_recovery is for OS restore) Can i take the short cut method???

Hallo
For your question:
make_recovery or make_tape_recovery are commands that make a tape that you can recovery your system in case your system was crashed! Of course, when you take a make_recovery or make_tape_recovery all of the OS' information (in vg00) will be automatic include.
So that if you just want to backup data as you said (you just take care about recover the crashed or deleted file, no need to recover the OS) so that no need to use make_recover or make_tape_recovery.
fbackup just enought.
With fbackup, you can backup with filesize up to 8GB and frecover is the command will recover or restore the file that you backed up to any system or mount point that you want.


Hope this helps

Yes.

Make a full "-x inc_entire=vg00" as you do.

The tape consists of 2 sections:

the bootable beginning
the tar (pax) archive

It's very simple to get to the archive:

## mt -f /dev/rmt/0m rew # or whatever
## mt -f /dev/rmt/0mn fsf 1 # forward 1 file
(notice the "n" at the end of the tape device, for "no rewind")

Now you are at the archive and can use tar:
## tar tvf /dev/rmt/0m # to list it

or
## tar xvf /dev/rmt/0m blah # to extract blah
