Er...then perhaps I should take a few steps back and describe what
I'm trying to accomplish.
I want to use dump/restore for backups for a network of a
half-dozen computers. There is no tape drive available, but one
computer has a CD burner and a lot of free hard disk space. Buying
a tape drive is not an option for financial reasons.
It was my intention to do remote dumps to 640-Megabyte sized files
on the one computer and periodically burn them to CD. When it's
time to restore, it can be done directly from the CDs or over the
net' from the hard drive if the required files haven't been
If you can offer any suggestions as to the ``right'' way to
accomplish this, I'd much appreciate it. As it stands, a short
script works to create and label the remote files and start the
dump. I haven't finished working on it, so I can't report if
the dumps can be reliably restored, but quick checks indicate
everything will be okay.
I'm aware of Amanda and not interested in it--it's overkill
for this network and, last I checked, didn't work well with
incremental backups. I also prefer using simple, standard tools
that I can count on to always be on hand.
P.S. If you'll permit a moment of dreaming...it'd be nice to have
a psuedo-device that makes a CD work something like a write-once
tape drive--oh, and throw in multisession support, while you're at
it. It'd be way more work for me than the end result would be
worth, but I'd be happy to use it if anybody else feels so
inspired. If it'd be easier to do than I think, feel free to point
me to some docs and I might re-consider. b&
