[Re: backing up large filesystems]
From: email@example.com (Brad Miller)
Are there better solutions to backing up a large filesystem than 40 megabyte
cart tapes? We now have ~20 tape full dumps and expect to double that soon.
RTAPE even between two lispms is usually flakey-flakey. Our CE doesn't
recommend using the tape except locally as a result of our and other site's
experiences he's run into....
You can also get a Cypher drive for your lispm... I'd recommend that over
our backups started getting huge, so we broke down and bought
the 6250 9-track tape drive for one of our file servers, and
it reduced 10 or 15 cart tape backups down to two or three reels,
which is a real improvement (we are actually backing up regularly
we have had some trouble with RTAPE between two 3600s, but recently
our Field Engineer put a 3670 i/o board into the machine with the
tape drive, and the problem appears to have cleared up (Hopefully
this will also fix the problem with irreproduceable Disk Search
Errors during gc-immediately that we were plagued with.)
