The short answer is yes you can.  The thing you have to do is use password
less keys for RSA authentication.  This way you don't have to have a password
in order to automate the backup routine.  Essentially you end up doing 
something like:

	find . -print | cpio -ocvB | 
		ssh account@your.host dd of=/dev/rmt/0 -obs=(cpio block size)
	
You can of course use other programs than cpio (ufsdump for instance).
To restore its something like:	
	
	ssh account@your.host dd if=/dev/rmt/0 -obs=(cpio block size) |
		cpio -icvB  

The other thing you might find is that you need to prep your tape drive
(turn on compression or a particular block size support) with mt.

Another fruitful thing to do is to just do a search on "ssh" and "ufsdump".
I have been down this road before, so I know such a search should help
you.  

CAVEAT:  Its been a while since I did this, so I may have forgotten some
minor point.  My suggestion is to read your man pages on dd, mt, cpio and
ufsdump, along with any tape device documentation you have.

Cheers...james
