Don't know of a built in option (not saying there isn't one - just
haven't used one) for this. However you could very easily script it.
Just do an iterative process where you position the tape with the mt
command then do the read with tar then move forward to the next record
with mt (fsf option) and do the read with the tar from there.

Subject: [Veritas-bu] Restore NBU tape with tar command?
=20
I am in the process of putting together a disaster recovery plan in
case our primary server goes down. This server is a stand-alone NBU
server, backing up only itself, etc. I have no problems using NBU to do
the recovery (bare metal restore, etc.), but those above me also require
a vendor-independent recovery plan, in case there are "problems" using
NBU to recover the data. I have experimented with using the NBU version
of tar, and have successfully restored files from the tape. My only
question is this: is it possible to make tar continue to the next backup
set on the tape automatically? Currently, I am only able to restore
small pieces of the system at a time (looks like 2000k or so). I am
familiar with the option to span multi-volume archives, but I would like
to see if there is an option to (for lack of a better way to put it)
start at a certain point on the tape and restore everything from that
point on, without prompts for user intervention. (The requirements for
the DR plan dictate that a user with little or no admin experience
should be able to do the recovery... this is NOT my requirement, but one
put on me by those above)

Any help/advice would be greatly appreciated!
