errno 75 is EOVERFLOW, which I think is probably related to 2G file limits in 
the backup software.

Or down to one machine. You dont have to put ZEO server and application 
servers on seperate boxes.

Today it is a single point of failure, so make sure that one box is well 
engineered.

Keeping a cold standby ZEO server isnt hard, if you dont mind a disaster 
losing a few recent transactions, and causing maybe an hour of downtime while 
you swap the boxes. There are several options for maintaining this 
replica.... Is that what you had in mind?
