> Put a [xfs]dump in cron.

from what I've heard, dump may be dangerous on linux 2.4 kernels. something
to do with how buffers and raw devices are handled now, as opposed to how they used to be.
I've heard of FS corruption due to dump (even on a supposedly real-only FS)
(something to do with dump reading something, which then gets cached, and
then somehow the cache then being written out... it was on lwn.net a few
months ago; but I can't find it right now).

in any case, it may be dangerous to use dump on a mounted filesystem; since
it reads the raw device, as opposed to what the kernel tells all the other
programs the filesystem looks like. you may not get a completely clean
backup.
