I have a SUNBlade 100, Solaris 8 operating system, two Ultra-SCSI cards. I
have been having a lot of problems with my backups to tape in the last month.
I tried installing replacement tape units (all are Exabyte 8505XL - one a
newer model with a wide SCSI connector). The backups worked okay on the
replacement units for a couple of days, but then they started failing. I
cleaned the drives and still have problems. These units are really old and
had not been used at all for more than five years and had never been used very
much at all even before that because our backups had been done over the
network until about a year and half ago. Since none of these drives were ever
used very much, I feel surprised that none of them seem to work properly.
Currently only the newest unit with the wide SCSI connector is sort of
functioning, but backups that were set up to be done overnight usually have to
be done manually in the morning because of I/O errors. I have a whole load of
new tapes, but it has been my experience that new tapes often don't work very
well on the first try, so maybe the new tapes are aggravating the problem. In
any case, I am feeling desperate and am wondering if a new tape drive might be
the best solution. I have a lot of still unused 8mm tapes and would kind of
prefer to go with something reliable that uses 8mm tapes as these are not very
expensive. We don't have a big operation here. The backups on weekdays only
require 112m tape (5.0 GB), and for the weekend backup I use a 160m tape (7.0
GB). I would be very grateful for any advice and recommendations that anyone
with more experience might have, including getting my current tape drives to
work properly.
Thanks in advance,
Marian Russell
