This is dream world stuff. How would it deal with referential integrity and check constraints and transactions that are predicated on the basis of previous transactions? How would it trap the communication between the application and Informix? I don't know all the players on the market but have a chat with Spectralogic on library@spectra.wall.com (+1 303 449 7759). They have a tape library system and Alexandria backup software that can do mass backups using ontape. I'm not fully upto date with the details on fully online backup but it does appear to work even though it may not be legally supported by Informix. It will be fully compatible with the new mass storage backup software API that Informix will be releasing shortly.
