Does anybody know the best way to back a filesystem up in RedHat5 onto a
set of zip disks?

 What ever you do, don't just copy the files over.  Even if you keep all the
permissions and ownerships, things will still get really screwed up.  Esp. the
RedHat Package manager.

1. APC USB ups, Back-UPS ES series, 2.5.68

(Please cc: me on reply)

I'm wanting to get this new toy up and running.  I've installed apcupsd,
but it doesn't want to work well with my kernel (2.5.68) or somewhat.

When apcupsd tries to open the hiddev, open() gets an ENODEV.  Is
apcupsd doing something wrong or is 2.5.68 doing something wrong?

p.s. apcupsd needs patched to handle hiddev from 96 on (minor allocated by kernel)
