Here is how I do it: I have a 300 MByte WrenIV, and have partitioned
it into 4 "disks", one of which I use for backup. 

First I made a complete backup, and ftp'ed that to a UNIX host where
its backup system took over.

Thereafter, every night RetroSpect automatically archives the changes
of the day to an archive on the backup partition. Later in the night a
UNIX shellscript automatically ftp's to my mac (using NCSA telnet as
ftp server software), and fetches the backup file, using macbinary
representation. If you want to (I do not) you can then ftp an empty
file to the mac, thereby essentially deleting the archive file. The
UNIX backup system then again automatically does its thing.

The whole thing is fully automatic, I have a backup no more than 24
hours old of my most important documents, and I am told if things go
wrong (the UNIX program sends me mail). 

The ftp server is password protected, so only the script (or anybody
breaking into the UNIX box and getting the password from a protected
directory there) can access my mac files.

Prerequisites: NCSA telnet (free), RetroSpect (or other archiving
utility, preferably with autolaunch), enough free space on your disk
to handle the archive files.

If you have little free space then you archive only pieces of your
file structure at a time, e.g. out of my 300MByte I keep 80MByte
available at all times, and back up my partitions in chunks of less
than 80MBytes (Sundays: Programs, Wednesdays: System stuff, every day
except these: Documents).
