Yeah, AT&T threw out "dump" and "restor"(sic) for the V7 file system and
its S5 descendant a while ago.  If you're sufficiently ambitious, they
can be retrieved from a V7 or 4.1(sic)BSD tape, although they'd probably
require some tweaking to work with the different block sizes supported
by the S5 version of the V7 file system.  The 4.1BSD versions are
probably the best ones; note that "restor" (yes, there's only one "e"
there) isn't quite as capable as "restore", although if you're willing
to sink this much effort into them you can probably improve it further.
