CFEngine2BackupPC

I'm tired of configuring BackupPC. CFEngine knows all my servers anyway, so can't it do it for me?

Automatically Adding Hosts

# Purge Bogus Hosts
cfshow -s -P

# Come up with the list of hosts. Best way I can do it right now
for HOST in `cfshow  -s -H | grep e0fff | html2text`
do
grep -wq ^$HOST /etc/backuppc/hosts || echo "$HOST 0 backuppc" >> /etc/backuppc/hosts
done

/etc/init.d/backuppc reload

Of course adjust as necessary. If your backuppc server is somewhere else you have to push the file, etc.

Automatically Handling SSH Host Keys

CFEngine should be systematically adding your backuppc ssh key anyway. But follow this guide and you don't have to worry about adding the host key to the known host file: BackupPC With SSH Authentication
