I'm looking for a 1 to 10 GB SCSI tape backup drive for my 4000 system. Does OS 3.5/3.9 have support for these drives? Is there backup software that supports this type of drive?
thanks

I'm using a Sony DAT DDS2 drive (4-8gb) together with Diavolo Backup to backup my Movieshop projects on my OS3.9 DraCo and it works great. So it should also work on your A4000. I don't think HDBackup supports tape devices but for example ABackup on aminet does AFAIK.

Thanks for the info!

yeah i had the same on my A4000T.. only with out the movie shop thing.
diavolo was a quality program, even had extras for backing up movieshop drives. ran fine with a DDS2 DAT drive (4-8Gb tapes.)
if you want faster backups / restores, have the tape drive on a seperate SCSI controller than the drives you're backing up.
e.g.
drives (fast stuff) on cyberstorm SCSI,
tape (slow stuff) on onboard/Zorro SCSI.
depending on compression settings, don't expect blindingly fast data xfer rates, even disk to disk is a bit of a nightmare, but i suspect that FFS is a bit to blame for that... :-)
oh yeah, DONT use DAT AUDIO cleaning tapes to clean your DAT DATA drive. or much pain and gnashing of teeth with prevail :-D

I don't see how it could matter on which scsi host you would connect both drives, as it's the slowest drive that limits the backup speed and not the controller? The slowest drive is obviously always the tape drive, as I don't even see a tape drive coming close to the speed limit of a fast-scsi host. Correct me if i'm wrong here...
about the cleaning cassette, normally you get a cleaning cassette with your dat drive if you buy it new I guess. At least I did...

well, its just a nicer way of streaming data... considering thats what tape drives do....
anyway, occasionally, obviously depending on the firmware version, but a read/write request sent to the tape drive might result in the tape drive locking out the SCSI bus to other devices while the tape drive sorts its life out. if the hard disk is on another bus, then the disk can get on with dumping data into the memory buffer while the tape does its thing. simplified example.

Diavolo Backup 2000 is really nice software, I use it for my backups on dat. It has nice scheduler etc. I guess there's some other software too, but haven't tested them :) One simple way to backup is to use btn tape handler to mount dat as volume and then you can pack with tar directly there for example.

currently using Travan 8GB tape drive SCSI bus and Ami-Back20. I could use Diavlo(?) for better software :-)
