Full System Backup

Danny Baldono — Wed, 03 Aug 2005 07:53:34 GMT

I have a two-node cluster with hpux 11i.
I would like to have a full system backup on
the two systems. On a normal system (not in cluster) I do a shutdown 0 for me to go to single-user mode to make sure that all files
will be backed-up then ofcourse mount -a. I know that without going to single-user mode, the file/s that are being used by the application or system will not be backed-up.
Now in the cluster environment would be for sure different. How to do the back-up on the first node then to the second node.

In clustered environment, most of the people keep the data on shared storage. So it depends on what you run under cluster. shut your apps/databases and ack it up.

But then, whay you need cluster-for high availability. You should then be taking a snapshot of files syetsm, make use of oracle rman and do backups.

This is where enterprise backups products are good at. You can have Legato Networker, OmniBack and Veritas Netback etc.

If you have ignite installed, you should perform a regularly scheduled make_tape_recovery of vg00. Backing up the rest of the vg's is dependent on the application on the shared disk. I assume the app(s) will have to either down or "quiet" in order to obtain a valid backup. In any case a commercial package such as OmniBack or Legato would be beneficial

To run the above command as given by Jeff first the system must have Ignite-UX software installed. Before executing the above command you must shutdown your applications which ever is running and it will take a backup of entire Root volume group ie VG00 in the Tape / DLT.

Please find the attached file for the better Reference.

There are a variety of ways to backups appls and databases. One way would be to use a product like RMAN as mentioed above for oracle. You could use BCV's if your san has them to make a clone of the data that y ou can detach from the running copy and run your backup of that as well. Many databases and apps have a safe way to put them into a backup mode so your backups will be valid. You will have to check with your vendors for that information.
Storagetek has an applieance that can sit on your san and replicate changes out which is pretty cool and allow you to take live snapshots of your storage.
