Not sure what to advise you (english isnt my language so forgive my mistakes...)
- backup isnt what we can call a standard command, I suppose you will see by typing file <path>backup as a script... and so I dont know what it does exactly...

- I suppose to go through as I would with such issue:
Get a tape head cleaner and have a go at cleaning the device
Prepare a new tape and insert it in the device

I dont know what commands are on a B class (worksation serie 700) I know only 800 (servers) but if you have fbackup/frecover command I would do a man and try to use these commands
Also tapes depending of which device was used DO NOT rewind after... and this may be why you cannot restore

I would do an ioscan -funC tape and it should display something like:
/sm/doc # ioscan -funC tape
Class I H/W Path Driver S/W State H/W Type Description
=====================================================================
tape 0 8/16/5.0.0 stape CLAIMED DEVICE HP C1533A
/dev/rmt/0m /dev/rmt/c1t0d0BEST
/dev/rmt/0mb /dev/rmt/c1t0d0BESTb
/dev/rmt/0mn /dev/rmt/c1t0d0BESTn
/dev/rmt/0mnb /dev/rmt/c1t0d0BESTnb
You should have your device on /dev/rmt/XmY
X=0,1,2,3...
Y= <blank>, b, n, nb
the meaning of Y is b for best n for no rewind
the idea is once we know what device to use, lets say /dev/rmt/1m
we use the no rewind device in order to use the mt command
once ready lets see if the tape is at the beginning:
mt -t /dev/rmt/1mn rew
# What is the result? (is it rewinding? proving you were at the end of writing explaining why it had nothing the restore?)
mt -t /dev/rmt/1mn offl to after, eject the tape.
