backup

hi all
i want to do a backup of the vg00 of all our servers and at the same time do a make_recovery tape. is it advisable to do both backup and make_recovery or one will one do?
i've downloaded the latest ignite from the web but having difficulty installing it, i get "can't establish lock on this target"
i downloaded it, tar -xvf<>. I put it in the /var/spool/sw, should it be in another directory? i use swinstall and swinstall -s.i get the same error.
the tapes that i'm using do they need to be brand new, if not new, do i need to initialize it.
thanks for all your help

hey jedd,

very advisable to do both, however it all depends on the intended use of each. first if for no other reason, two backups are better than one (especially if that one fails). Second although you can retrieve specific files from each an fbackup is a whole lot easier to retrieve files from (frecover will save you alot of time, rather than trying to fsf the tape and find what your looking for. Our disaster recovery, we make two make_recovery and two fbackups of vg00, just incase of tape failure (sometimes they go bad) As for the question about using new or old tapes usually the newer the better due to tape fatigue and stretching, but you can sometimes get away with used tapes this should be based on how critical the sever is and how used the tapes are (new tapes sometimes go bad too).

The install issue, if you are sure you have a good download of the product, and are having problems with the install from the command line reguardless of where you have located the product (assumeing the mount point has enough room for the extracting of the file), try installing it by running the gui for swinstall and pointing the location to the file its self, and installing it that way.

hi, thanks for the quick reply. what you suggested about running the swinstall gui, that's what i've been doing, bur for some reason, it won't go through, it complains,"it can't write a lock" i downloaded my ignite ux software on /var/spool/sw and tar -xvf in the same directory. i still can't use swinstall. is there a bug? i'm running 11.00 on
HP-UX 700 that's what i'm going to be using for my ignite ux and backup server with tape drive attach to the 700.

im not real clear on what your having problems with, as you know there are different stages that swinstall takes you through, it sounds as though you might have a problem with swinstall its self. do a ps -ef | grep swagentd, you should get something like "swagentd -r"
if you see the man page on this, you can run swagentd -r from the command line and it will stop and restart the swagentd daemon. Then try this again. If you continue to have problems but are convienced that you have a good copy, do a search on swinstall problems. hope this helps

Hi Jedd.
You should do both backups. Backups are always welcome.

To install your latest ignite you shouldn't untar it! Install it as you download it.

other thing is, you should run "make_tape_recovery".
good luck.

As far as the backups go, the advice above is what I would have said.

I suspect your download is OK. The depot is a tar file itself so doing the tar xvf <..> will ruin the depot! you need to install from the tar file!!

e.g.
ftp the file ignite-ux.tar to /var/tmp/.

Do s preview non-interactive swinstall
# swinstall -s /var/tmp/ignite-ux.tar -p \*

if all is well, do a non-interactive swinstall.
# swinstall -s /var/tmp/ignite-ux.tar \*

If you prefere the interactive version of swinstall drop the "\*".
