Hi there.
That depends on the software you have installed. Using fbackup is one chance.
Use this in line mode, if you backup files of more than two GB.
Next would be cpio. sample :

today_=`date +'%y-%m-%d'`; export today_
#
LOG1=/usr/tmp/cpio_${today_}.1st; export LOG1
#
PATH=$PATH:/usr/local/bin
export PATH
exec > /usr/tmp/cpio_${today_}.log 2>&1
#
#
find / -depth -print | cpio -ocBv > /dev/rmt/0m 2>> ${LOG1} &
first_cpio=$!; export first_cpio
#
wait $first_cpio

if test $? -ne 0; then
echo "Full Offline Backup did not complete successfully!"
fi
echo "Time is: `/bin/date`"
echo "Time is: `/bin/date`"
echo "Time is: `/bin/date`" >> ${LOG1}

Next chance is OmniBack II, but this is a piece of software, that costs some money.

Hi thanks for this but will this back up the operating system as well as all the partitions and all data?

first i would install ignite, and run a

make_recovery -Ai

this will backup all of vg00 and allow you to boot off of that tape if you need too.

next i would run an fbackup on /vg00 only

bdf | grep vg00 | awk '{print $6}' > /tmp/graph
bdf | grep -v vg00 | grep -v Mounted | awk '{print $6}' >> /tmp/graph

vi /tmp/graph (for all vg00 put an i for all non vg00 put an e in front of each mount point eg..)

i /
i /home
i /var
e /vg01mountpoint
e /vg02mountpoint

save this

now run

fbackup -0 -g /tmp/graph -I /tmp/fb_log -f /dev/rmt/

=ioscan -funC tape (fbackup will choose /dev/rmt/0m by default, so you can leave -f /dev/rmt/ off first if your not sure and make sure there is activity on the drive after you start it)

after you do that, change all the "i" to "e" and vice versa in the /tmp/graph eg..

e /
e /home
e /var
i /vg01mountpoint
i /vg02mountpoint

now run the fbackup command

fbackup -0 -g /tmp/graph -I /tmp/fb_log2 -f /dev/rmt/

now you will have your:

vg00 tape
non vg00 tape
make_recovery tape (to recover a full OS if needed)

let us know if you need more detail, good luck, if your not sure about the tape device, put and ioscan -funC tape on the forum and some one will help you out.

Once you have the basic files (like Boley said), it wouldn't be a bad idea to setup a backup routine to backup all the files on a regular basis. Either send the command to cron or you can set up the backup through SAM (backup and recovery > automatic). Just specify the folders you want (include /, exclude /tmp, etc) and tell it when. Works well, and emails problems. You only need to so the make_ignite tape when you change the OS (we do our quarterly if there are no changes).
