By the way, this device is somewhat pricey. I paid $403.95 for it in early
'03. There may be cheaper networked devices around that have the same
functionality.

I have a Linksys EFG80, which is an Ethernet networked storage device. It
is a Unix based operating system running Samba, which is designed to be used
on a Windows network or workgroup set-up. If you install Samba on Linux,
you can back-up directly to it. It comes with one 80G drive and a slot for
a second drive up to 120G. I used to back up directly to it, but my backups
got so big that CP would crap out about 2/3 of way through (maybe I was
overflowing buffers on the Linksys). The device also has an FTP and Print
server. I now log into it via FTP and do a "send". That way, it controls
how fast it wants to move the data and I've never had any problems. I have
both a Windows and a Linux machine on my network. My printer is hooked up
to this device and I can print to it from either printer. It's a pretty
handy device for a small home network. Just an FYI.

Yes, you do get a backup of modified files. But those not modified, that
came from an rpm on CD are no copied. It is a kind of incremental restore,
such a one that a full restore can be a real pain. I know, it happened to
me.

I do my backups manually. I use "mkzftree" to create a compressed tree of
files and directories which are a copy of everything on the HDs I want to
backup. Then I break them in chunks roughly 4.7 GB (using mc). Those
compressed trees I convert to images using "mkisofs -z -R ...", which I
finally burn to DVD using xcdroast.

The result is two DVDs with a full compressed backup of my Linux
filesystem, which can be mounted normally (mount...) and explored or
restored using any standard Linux tool, like konkeror, midnight commander
(mc), cp, whatever: zisofs compressed CDs/DVDs can be read transparently
by the Linux kernel, they are decompressed on the fly.

It is a complicated way of doing a backup, and needs about 160% of your fs
as free space. But the end result is very usable.
