What is the "volume" when using ufsrestore in Solaris?

Question

I create a backup of a Solaris system with ufsdump and the backup spans multiple tapes.

When I use "ufsrestore isfv # /dev/rmt/0" to recover a file interactively, I am always prompted:

"Specify next volume #: "

What exactly is the volume number? If the backup spans 3 DAT tapes for example, is the volume number the same as the tape number in the backup?

Answer 1

yes it is the next dat #
