That's what I use too. I use it with rsync over ssh as root, with the
remote set up for root to run forced commands only, and in order to back
up different trees independently, I use different ssh keys, each with
its own forced command. That's a bit fiddly to set up, but seems to work ok.

Can you elaborate on the performance issues? I'm using dirvish for my
maildirs (dovecot imap server), without noticeable problems.

One change I do make is to enable 'dateext' in my logrotate config, so I
don't end up with endless duplicates of my logfiles due to the names
changing.

My current challenge is to back up windows boxes - if I can get rsync to
work (maybe DeltaCopy? Not sure if that will work how I want), I guess
I'll be stuck doing a local rsync of a smbfs mount ... unless someone
has a better suggestion.
