I have read about not doing a direct sync over a wan because of
the potential for corruption. As I understand it, the replica
that is not local to the requesting replica is copied across the
link and updates are made in both direction. I also understand
that if the link breaks or disconnects, that corruption can occur.
My question is whether the potential for corruption is on both
replicas or only the one at the far end, which had to send data in
blocks across the link?
The potential for corruption is in the remote replica, though I
guess it could happen in the local one, too.
Direct synchs should never be done over a non-wired LAN connection
of anything less than 10Mbps bandwidth.
