I've got a Workstation Solutions ExaTape 8mm tape drive, and I
think it's the bee's knees. It came with a SCSI interface card
and support software for doing rwmt, tar, rbak and wbak. With the
capacity of 2.3 GBytes per tape, I can back up my entire system,
including all of the OS directories if I wish, overnight.

I'm not going to SR10 until the summer (actually, I'm leaving my
job here for one with Exxon, and my replacement will have to learn
a lot before doing an OS update), so I can't say the effects of SR10.
The guys at Workstation Solutions seem to really know their Apollo stuff,
so I'm fairly confident that there won't be a problem.

Depending on the machine you connect the drive to, you can get the following
data rates (depending on network traffic or whatever else):

           DN4000:        256 K/sec
           DN3000:        128 K/sec

You might want to confirm those with a call to the company.

To back up 2000 Mbytes (2 GBytes), it takes me about 10 hours, but it's
so automated, I just swap tapes in the morning. I have a shell script to
wbak chosen directories every night starting at 8 p.m., and it finishes at
4:30 a.m.

Good Luck.
