Re: 6390 data capacity

Dan,

I believe the tape is rate for 3.5 GB of storage uncompressed.  With
compression you can get up to 7.0 GB, however this largely depends on what
kind of data you are backing up.  (E.g. program objects and database objects
back up with significantly different compression ratios.)  So if you can get
2:1 compression you will get 7.0 GB on the tape, but if you only get 1.5:1
compression then you will only be able to fit 5.25 GB on the tape.
