specific folder update / rsync

Log from IRC server Freenode (IPv6) channel ##Linux.

<me> hi, I'd like to backup some file from a server then send it to another server with a simlar file structure which is like /var/qmail/mailnames/domain/accountA/Maildir/new for all the accounts of the domain then I'll go on the other server and add all of those files to the same directories which migh already contain some files. This would be very tedious manually, if you have any lead about...
<me> ...commands, pages, techniques or searches, it would be of great help. Thank you.
<PeterFA> me, try rsync.
<ananke> me : rsync
<me> PeterFA: ananke : I'm on windows but have SSH access on both servers, would that still be feasible ?
<ananke> me : yes, as long as you have rsync binary available on both ends
<me> ananke: so both servers will transfer files to each other directly or I'll need to d/l something on this badly OSed station ?
<me> ananke: PeterFA : the directory structure I posted includes other files and folders but I need to only transfer what's in the "new" directories, will I need to pipe the information through find first ?
<me> a/through find first/from find first
<ananke> me : maybe you should read about rsync in a bit more detail
<me> ananke: I'll do, sorry I'm nervous, I thought by the time I'll be ready for my next question you'll be gone and will have to reexplain to other good samaritans
<me> ananke: my boss think it's too risky this time so another time ! :|
<ananke> me : uhmm, that's why there's --dry-mode in rsync. not to mention, you shouldn't be experimenting on production
<me> ananke: thanks
