If it's possible for you to take down the machine, you could do
a bare-bone network backup via dd and netcat:
Boot from knoppix cd
set up network
on the remote machine, enter
nc -l -q 1 -p <some_port_no> > /path/to/backup_file
on the local machine
(assuming your disk is /dev/sda
dd if=/dev/sda | nc <ip_of_remote> <port_no_as_above>
You might want to put a gzip into the chain as well.
If so, it's also a good idea to mount every partition before and doing a
dd if=/dev/zero of=/mnt/<yourpartition>/zero
until it's full and removing the file. By that your empty space gets
overwritten by zeroes which is a good thing(tm) for compression.
Replay in reverse order.
As this provides an exact copy of your device (incl. MBR, etc.),
make sure the hardware does not change before replay.
