Please elaborate. My purpose would be to be able to keep a FB database on a RAM disk for performance reasons, and have a replicator keep a copy on a regular disk for backup purposes. This copy should be as up to date as possible, transaction by transaction. Are there no replicators that can do this? In my system there are no generators, SP:s or even triggers. It's as plain as it gets - maintained by an OO mapper that ensures ref integ etc. So there are indexes for foreign keys, but no fk constraints (because, I assume, it would complicate things for the OO mapper).
