Tape archiving systems

[utzoo!duke!decvax!ucbvax!CSL.JLH.MOGUL at SU-SCORE]

We are interested in finding a system (to run on our 4BSD Vax Unix)
that allows us to
	(1) Move selected files onto tape
	(2) record someplace (on-line) what files are on what tapes
	(3) retrieve files with a minimum of bother (i.e., not require
		a wizard to retrieve)
	(4) efficiently use tapes (i.e., not partially fill them)

tar might meet (1) and (2), but the current manual entry implies that
the r flag cannot be used without the c flag; thus (4) becomes 
difficult unless we batch files by the tape-full.  (2) would probably
require some minor modifications to tar.

If anyone has something like this, please let me know.
