In our office we have two Performas & one Quadra connected, set up with Jaz & Retrospect for automatic daily backups. They were installed professionally in October. The installer could never get it to work consistantly. I switched "experts" in January. It's still not working. It'll work for a few days after the computer rep fiddles with it but fails within a week, for a variety of reasons: disk full; does not recognize the disk; not a macintosh disk; on and on. I don't want to put any more money into this system ... can I dump Retrospect and just use the Jaz drive/tapes for manual back-ups, dragging files over like the old days?
