Yes, but the heal will then take three weeks. I have the data
at hand, so if can preload it with the trick I described,
I would have a full volume in a matter of a few hours instead.

Yes, I have pondered back and fro on this subject. I finally
opted for three full replicas because my underlying problems
of unreliability (flakey connections, the dynamic public
IP address of one of the peers) outweigh my desire for speed
and bandwidth conservation. To put it simply, a 2+1 volume
would make it easier and faster to store the data, but it
would make it harder to access it when one of the peers fails.
