I suppose this is more an rsync question than a dirvish question, but
hopefully someone can answer it.

I have several computers at my shop that I use on a daily basis.  I want
to back them all up with Dirvish each night. 

As discussed previously on this list, I could have a separate SSH port
for each machine or an SSH tunnel setup on the border router to forward
to each machine.  However, all of the data that really needs a nightly
offsite back up is on one of three machines - one is my main desktop and
the other two are already mounted as samba shares on my main desktop. 
My idea then is to backup only the main desktop, which would bring with
it the samba shares on the other two boxes.  The connection between my
shop and my house is at most 768k while the local network is 100mb so I
don't think flying the data across the local network will add much slowdown.

My question is what happens if the samba share is not there one night? 
If it's mounted on Monday, not mounted on Tuesday, then mounted on
Wednesday, will Dirvish treat Wednesday's files as new files and
download them again, or hard-link them to Monday's files?  I suspect the
answer is they'll be treated as new/changed files...unless the unmounted
share returns an error, in which case Dirvish would use Monday's
directory as its base for comparison, right?

Suggestions are welcomed.  I may end up just setting up cygwin/dirvish
and opening up those SSH ports for the two windows boxen.
