great! thank you all!
Unfortunately it is what I though :(
I`m building this guest as a live backup of a physical 64bit
machine running debian etch.
So, I think the best way, in such case, is to run a 32bit guest,
configure all services like the original and only make daily
copies of critical data (databases, mailboxes and some
variable confs like squid acls).
Yes, that sounds sensible. Be careful to take measures to ensure that the
backups are consistent; just copying the files that are in use by the
applications may result in inconsistent copies being made, which could result
in data loss. For really good reliability you ought to take a look in to
recommended backup practices for each app you want to sync data for.
Yes, normaly I use mysqlhotcopy for mysql, since all my DBs
uses myisam storage engine, and rsync (through rsnapshot)
for mailboxes, since I use dovecot/maildir for pop3 server.
Then, all the rest are static conf files, like squid.conf and others.
Thank you very much by the valuable info and tips!
