I talked with apunix computer services on the phone and they were very
helpful, technically and explained it this way.(as I decipher my scribbling);

A "NEW" version of backup Copilot, includes a "serial" driver for SunOS4.x.
The Exibyte "Tape Stackers" come in a 10 tape, 12gig/tape, one drive conf.
You can choose between a gravity drop stacker robot (10) which uses the
"sequential mode" driver. Retrieves have to go through the tapes sequentially
until the matching tape is found. Or you can choose a random access stacker
(10i), which uses a "non-sequential" driver, and can load the matching tape
into the drive immediatedly. This "non-sequential" driver is the one the
new version of backup copilot does not provide on SunOS4.x. The "sequential"
driver is provided with backup colpilot for SunOS4.x. You can get the
"non-sequential" driver from apunix computer services, but will have to
give the stacker commands from "outside" of backup copilot.
        Of course you can order the large stacker, but I don't know if
that comes in a gravity drop stacker robot type.
        They also mentioned to make sure the stacker has "QFA" which
remembers where on the tape the file is, so it doesn't have to search
for it, and can just fast-forward to it.

They also said that there is no difference between a stacker and a
        I am going to submit these questions to our local Sun office:

1. What is the New version of Backup Colpilot?

2. Does it include a driver for "sequential mode" gravity stacker robots for

3. Does it include a driver for "random access stacker robots for

4. If either driver is included, Do they work with just Exibyte Stackers
   from "within" backup copilot, or other stackers as well?

I will let you know when I get replies.


Boeing in Phila PA purchased a jukebox from us with device drivers, that allows
them to use backup copilot with the 8mm jukebox. They wrote shell scripts to
automate their backups.

They`re expensive! So far we only have several of their fast-scsi 2 drives (alsoexpensive), but they're good performers and very slick in appearance. I think I
heard a price of ~75k $CDN for the "Bread Box", but I could be wrong.

Yes, they do (work with SunOS4.x). I just found out we may be bringing one in to trial shortly.
