That's a relief.  I always hope programs are smart enough to lock files they 
change.

Then the lockfile will be created and deleted on the backup server as well.  
Since we kind of assume a master/slave situation with the two vm systems, I 
think this should work?  But talk is cheap and I've not done this, yet.

On the other hand, you might use the external notification option in 
voicemailmain to initiate the sync....

Not sure.  I only minimally support samba these days.

Hope this helps,
Mike.
