I am going to buy a tape backup system for MAC II. In order to save money I am going to buy a used one. Some one is selling a SCSI tape system used to be used for a SUN shoebox. My question: Can I use it with a MAC II? What kind of driver I need? Thank you in advance.

I have a Tandberg Data TDC3620 running, using FastBackII. All the problems I have seem to be bugs in the software (FastBackII cannot backup an 80 megabyte HD to 60 megabyte tapes, it seems). hase -- Hartmut Semken, Lupsteiner Weg 67, 1000 Berlin 37 hase@netmbx.UUCP Hi!

(Zaphod Beeblebrox) Ahem. I assure you that Fastback II *can* back up 80 MBytes onto a 60 MByte tape. I do it all the time. Data compression makes it possible. If you're having trouble with your tape drive, please email the details to me and maybe I can help. Dan Pleasant [Part author of Fastback II, but not the tape driver.]

Next I tried an 80 MB disk filled with Text files compressed with DiskDoubler and lots of GIF format pictures. FastBack II did not compress it any further, of course. But worse, FastBackII made me loose my data: after filling the first tape, the Backup dialog told me to "change the cartridge when it stops" and then to "insert volume <number 2>". I did insert a second tape and FastBackII reportet to write another 20 MB to it. No warnings, no error messages; only completion messages. But even after reading the manual - page by page - I did not find out how to restore the data from the first tape. The second tape restores fine. hase -- Hartmut Semken, Lupsteiner Weg 67, 1000 Berlin 37 hase@netmbx.UUCP Hi! (Zaphod Beeblebrox)

Sounds like Fastback did exactly what it was supposed to do! >But even after reading the manual - page by page - I did not find out >how to restore the data from the first tape. The second tape restores >fine. Just put it into the tape drive! Did you try that and it didn't work? As I said, I didn't write the tape drive code. I think, but I'm not certain, that you might run into trouble if you put the wrong kind of tape into your tape drive. Try contacting Fifth Generation Systems technical support. They keep track of things like that, and they'll probably be able to tell you what to do. >hase >-- >Hartmut Semken, Lupsteiner Weg 67, 1000 Berlin 37 hase@netmbx.UUCP >Hi!
