We run a network with VAXen, Sun Sparcstations, and a few 386 boxes
with ISC 2.2.
In order to have a uniform backup system across all machines, we would
be interested in finding versions of the dump/restore programs for
ISC 2.2. It is particularly important that these versions support the
use of /etc/rmt, the remote magtape daemon.
Does anyone have any hints?

Supports /etc/rmt, is fast, dumps are portable, does incremental save/reload, etc...; there is no need for dump/restor any more, even on BSD. Saving with tar is as fast as saving with dump, because the bottleneck is in any case the tape. Restor is faster than reloading with tar, because of the synchronized ilist writes of hardened file systems, but hopefully reloading is less frequent than saving. -- Piercarlo "Peter" Grandi | ARPA: pcg%uk.ac.aber.cs@nsfnet-relay.ac.uk Dept of CS, UCW Aberystwyth | UUCP: ...!mcsun!ukc!aber-cs!pcg Penglais, Aberystwyth SY23 3BZ, UK | INET: pcg@cs.aber.ac.uk

If you have source licenses (so you can get BSD tapes), try grabbing: 1) a 4.1BSD tape (yes, 4.*1*BSD - keep reading); 2) a 4.2orlaterBSD tape (the later, the better, probably). 4.1BSD had a V7-based file system, just as S5 from AT&T does (dunno how ISC's fast file system would get in the way here), so you can start with the 4.1BSD "dump" and "restor" (no "e" at the end). You'd probably have to whack on it a bit to teach it about both 512-byte and 1K file systems. Then grab stuff such as the support of remote dump/restore, and the more reasonable "restore" interface of the 4.2andupBSD "restore", from the 4.2andupBSD code, so you can restore files more conveniently by name, restore entire directory trees, etc.. Sorry, I don't have anything easier to suggest. Anybody done some or all of the above?
