Backups under ServiceGuard?

Chris Hodson_2 — Thu, 27 Apr 2000 10:43:33 GMT

What does anyone recommend for backing up data that
is in a ServiceGuard Cluster?

Backing up per host could lead to data being missed or backed up twice.

Backing up per service leads to weird configs and requires constant attention.

Any ideas?

For backup use the floating addresses, that way you dont particuylarly care
which machine the data comes from, but you will know, that you get all of your
floating data. Ofcourse, use the fixed address of each machine to do the OS
related just for that machine.
I have used Openvisions Netbackup successfully in a similar scenario without
any problems.
If you have any further questions, dont heistate to contact direct.

We use OB for all our other backups, so I would prefer
to keep using it.

Firstly you have to define the scope of backup. In a general SG environment,
you have clear demarkation between OS and applns.

So use HP Ignite/UX for creating a backup for vg00.

Once a fortnight, run a cronjob to fbackup the vg00 (if there are many changes
go for a weekly cron).

At a given time, you can use ignite and then the current weekly fbackup to
recover vg00.

As for the appln data, it depends on many factors. For more details you may
need to check with the DB vendor for the best methods. Generally, DBexport and
backup of redo logs (other wise known as transaction logs) is a trusted backup
method.

Good luck
