I used a modified version of Peter's backup over the weekend to move one box
to another. The backup he described contained everything i needed included
custom installed packages, there were only a few minor things i changed.

- his script creates the backup file in /opt, which quickyl ran out with
12GB to transfer, so i created it in /home/users/admin with a --exclude in
the tar

- The resulting file (approx 12GB) could not be transfered throufg ftp (2GB
max), so i ran a split to slice it into 1Gb pieces.

On the restore end;

- first restore the GUI, then REBOOT, or you will run into quota issues
during the restore for larger then default sites.
- Then, recreated the large file (cat aa ab ac > archive.tar) and extracted
it.

The only downside to the entire thing is that you must have a sizable free
space on the system to create your tar, and then for the slices. (2/3 of
your harddrive must be free.)

With the modifications for large sites/files, his script looks like;

#
# Backup script for a Cobalt RAQ 550 (and probaly other models)  server
#
# H.P. Noordam, version 1.12, 30 jan 2004
# http://www.dePoPo.net
#
# Original script by Peter Rombouts
# Some idea's from neuhaus' raqbackup
#
# This script backups the GUI and most of the rest of your server to a
directory
# from which the backup file can easily be retrieved with ftp.
(/home/users/admin/sitebackup)
# If you only work from the gui, this backup should contain everything you
will ever
# need to restore the 550 to it's original state after a failure
#
# this script has been tested with backup files of a maximum of 12GB (most
backup scripts
# fail to ftp when files > 2GB are encoutered)
# however, it is still a work in progress, and you WILL run into quota and
symlink
# issues with big restores with require manual handling.
# what seems to work best is; restore the GUI, restore the TAR file until it
breaks off with
# quota errrors, then reboot the machine, and re-run the untar command.
# During the second run, the correct qutoa's should be in effect.
