however, if your data is already compressed, around 150GB is the maximum.
Hope this helps!

So to determine if your data can be compressed, you'll need to run compress on each file to determine approximately what the compressed size will be. Then expand the file back again and add the result to your total. The total for all files will roughly indicate how much tape will be needed.
In other words, you are getting the result that the tape drive can produce -- your files are not very compressible (typical for binary files) so you will only get 150-160 GB maximum.

Your best bet is to see if there are any temp files (or other files)that can be deleted (or just mount a second tape).
I agree with Bill, the tapes should list their native storage capacity when they market them.
