[stuff deleted] Yes, there is a whole manual with hundreds of pages called "INFORMIX-OnLine Dynamic Server Archive and Backup Guide Version 6.0", because it is so different. You can use multiple tape drives simultaneously, schedule backups, compress and encrypt, backup by dbspace, restore part of an archive, and lots more goodies. I have taken the class, but the upgrade tapes have not arrived yet, so I don't have much experience with it yet. -- Roger J.
