If you have three hard discs, the server has built in software RAID.

Not really. You could monitor the syslog output and detect when a 
client disconnects, I suppose.

However, you could just not worry about it, and let the sync tool just 
do it's thing. If you needed to use the backup of the backup, then you 
can use the account fix tool to get everything to a state where you can 
get the files. The worst that could happen is that a file or directory 
is in the "lost+found" directory rather than where it should actually 
be.

Eventually you will be able to replicate an account to another server. 
When the client disconnects, changes will be transferred efficiently to 
the backup server. The existing code is written with this in mind.
