Make_recovery

[TANHM]

Hi All,

Is it possible to restore one or two file system - user data (Under vg00) only from make_recovery tape? The system only has one vg which is vg00 therefore i am thinking whether i can backup by using make_recovery only (save the trouble by backing up the data using fbackup or tar).

Hi,
you can restore what you want.
To extract a single file (directory) from the recovery archive:

mt -f /dev/rmt/0mn fsf 1
tar xvf /dev/rmt/0m filename_or_dir

Still see as whether you have vg00 with huge size disks.

I would suggest to take a image of the system file systems using a make_tape_recovery.


Other non-OS file systems can be backed up using fbackup.

The important objective of the make_tape_recovery is that to build a image of the system and to use it whenever required in a faster and effective way.

Impossible,
make_tape_recovery is used for backup all data in your system (vg00). when U restore all data will be restore. You can not choose which filesystem to be restore.

That all

make_tape_recovery is great for backing up your boot VG(vg00).

Once you have a tape, it is easy to restore files from it. It may be time consuming though.

#Make sure your tape is at the very begining.
mt -t /dev/rmt/Xm rew
#From the man page for make_tape_recovery:
#Position your tape to file 1. File 0 is the boot part of the tape.
mt -t /dev/rmt/Xmn fsf 1
#Extract the file or directory you need from the tape.
tar -xvf /dev/rmt/0m filename
