Here is my strategy:
Backup via cp all domains in /home/httpd/vhosts/* (from ./vhosts/cp -R -p * /spare/backup/ )
Backup via cp all mail in /var/qmail/mailnames/*
Backup via dump all databases
putting all this on a slave drive.
Then, requesting a server restore (now comes with RHE4 & PSA
for a fresh install base, then cp'ing back all the above and upgrading the mysql db's if necessary.
So, my question is, will this work without a hitch? Looking for potential problems before I get started.
