Recovering Catalog

[wamason]

I have a project to recover some data that backed up with a old Netbackup master server. The data is going back 3 years ago. if I have the tapes that were created on the specific day how can I tell which tape has the catalog backuup on there?
I am assuming that once I fine the tape with the catalog i will then run the bprecover command that will recover all the images that were backed up. Am I on the correct path?

Yes, well sort of.

bpreover will attempt to rebuild the library and tape drives. You probably don't have the same configuration available.

You could also import the tapes.

Thanks for the response, but I have the tapes and the tape numbers are on the tapes, I just don't know which one has the catalog backup. Does the catalog backup write anything unique on the header?

yes

another way that may have some risk involved is to run bplabel on the tape.

The tape will be mounted and it will tell you if it already has Netbackup data or if it is a catalog tape.

It will then give you a yes/no question on whether to continue.

You MUST answer no to the response or else you will forever lose what was on the tape if you accidently answer yes and actually run the bplabel command to completion.
