But doesn't that just move the potential conflict to the delta file,
leaving you with the same issue but in a different place? I don't see
that it really improves things all that much.

Well, on further thought I suppose the original database file could then
be thought of as internally consistent as of the time NBackup was
started. Is that what you were getting at?

But none of those are really an API designed for this specific purpose.
Do any backup systems make use of NBackup to control a Firebird database
during backup operations? Anyone know?
