The reason I got interested in replication is the availability of an 
up-to-date backup at any time.
If the primary server were to crash, for example due to a disk crash, the 
existence of a mirror repository allows to be up in a matter of seconds. 
Simply change the hostname of the backup server and some CVSNT settings 
and the backup can replace the original server. 

Indeed, you don't really need sync for this (using unison or rsync alone 
would offer the same live backup), but when I started out reading up on 
the replication I didn't know that and believed the sync protocol would 
take care of all the replication.
