The ON-Bar utility will be available with the 7.21 release, and will be device-independent. It will not care what the characteristics of the actual tape are (wound, re-wound, compressed or whatever) because it will use your choice of storage managers. ON-Bar will manage the Informix side of the archive process, and the XBSA server will handle the storage media. As an additional bonus, the command set is simple and the error handling is very thorough. In the meantime, you should be careful how you manipulate the archive process. While it is possible to do nearly anything (this is Unix, after all) as the archive gets more and more complicated Informix will have a harder and harder time understanding--and thus supporting--your system. If you follow the Informix guidelines to the letter, then the support team already knows the "boundaries", and has tools that can help in the event of a problem. FWIW, I've been on both sides of this issue, and empathize greatly. I can hardly *wait* for ON-Bar.
