The minor detail is that it's a TERRIBLE way to find out the your archive tape drive or media has gone bad and that your archives for the last month are shot. Since Informix provides no way to test your archive tapes, I would never take a restore test lightly, especially on LIVE data. (We 'dd(1)' our tapes regularly to make sure we can read them as a test of backup validity, but it's hardly fool proof. If the tape drive decides to write 2G worth of NULLS, dd won't know the difference.) > > Scott Fly aware... Will (villy@collinscomp.com)
