I have read the message with interest, as i saw this behaviour ( maybe a
behavior that seems related ) in IB 5.6, i can send to any one
interested unrestorable bakups from perfectly valid Databases, due to a
table that was duplicating his unique keys, but our problem was related
to the use of triggers in updatable views, it's a hard to reproduce
problem, after finding this inconsistency everything seems to run
smoothly.. until now i must say, because we are not very sure if the
problem really was this..
