The compression ratio isn't something you can control - you get the best
that your hardware can give.

No this is just one way. You have a choice of compressing the data at
the client side, or letting the compression hardware in your tape drives
do the work.


Davina: Thanks for your response, can you shed some more light onto
compression from your hardware in your tape drives. I was wondering if there
is any setting on the tape drives i should take care of.

Peter gave me a good insight, i was wondering if there is anything i should
be taking care of

I am more concerned about the following error message
