Re: 400GB Tape
Which software you are using for backup ? Is it Dataprotector or some other backup software ,if so you can use the entire capacity of the media.

Re: 400GB Tape
So are they 200/400GB tapes or 400/800GB tapes?
Because indeed, those compressed capacity are assuming 2:1 compression ratio, which sometimes cannot be achieved, or sometimes can be higher than that, depending of the type of data being backed up.

Re: 400GB Tape
*Assuming 2:1 compression
This is mean 200/400Gb or 400/800Gb?
i think this 200/400Gb?
That's right?
Thanks
