Re: DLT IV Tape Capacity

Careful. You're mixing apples and oranges. No doubt, the Legato number
reflects pre-compressed data, and ADSM post-compressed. Even so, I
wouldn't expect numbers as high as 200GB. That would indicate almost
6-to-1 compression.
We are seeing on average about 32.5-33.5GB per tape (CompactTapeIV on
DLT7000). We use client compression but not tape drive compression.
