backup without stopping the imap server?

From what I recall (which might be fuzzy - someone please correct me if any of
this is wrong!) there is no way to do this properly. There's some stuff about
it on the wiki isn't there? Think I remember seeing something about using LVM
mirrors to do it best.
Basically, you have to stop the server, backup (split a disk mirror
would be the
quickest no doubt - but I rsync the store to another local disk), restart.
Once you've split your mirror (or done your local rsync in my case)
offsite, etc. from that.
This is what I'm doing but it's not ideal. Would love to hear if there's a
better way. I can only get away with it due to the small number of
users at the
mo, but as things grow will defo have to re-think this.
I'm hoping that this murder thing will come to the rescue and allow a backup
over slow/flakey connection without interrupting the master server. Is that
possible? Going to be the case in the future?
