RE: TBTAPE Level 0 Multiple Tape Archive

Date: Friday, 12 January 2007, at 10:20 a.m.

In Response To: RE: TBTAPE Level 0 Multiple Tape Archive (Clifton Bean)


No 'compressed' devices on AIX that I'm aware of, but most of the drives have a
way to turn compression on as the default. Be aware that the compressions
algorithms on the drives are optimized for text and are mostly doing run length
compression. They get about 45-55% compression on pure text but closer to
10-20% on binary data. Any AIX SA'a out there that know of an OS level util to
set the compression on these drives?

While I am waiting for this customer to order and receive some larger
capacity tapes -- and even this is only a temporary solution to them staying
on one tape ...

It has been a long time since I have used such a creature but isn't there an
equivalent to /dev/rmt0 that signals to perform compression at the UNIX
level? For AIX 4.3.3? Does it play well with Informix's tbtape restores?

I am wondering if there was an environment parameter available that would
"ENABLE_COMPRESSION" that would allow the backup to become compressed as it
is written to tape and be recognized if (when) it comes time to perform a

Any ideas?

Thanks in advance and have a good weekend.

It wouldn't help with your efforts to get an upgrade, but is there any
chance of fitting a larger capacity tape drive?
