I confess that I've never used compression on tapes before, ever.

The tape says it is "800GB/1600GB compressed" so I am just going by
what the tape says, assuming it is the way data gets written to the
tape rather than an implementation of a particular algorithm.

Thanks, I am looking at this but as I have 1.5TB of data that's not
going to fit on a single tape no matter the compression type, I'll
need to span or break it up anyway. In which case I may as well not
bother with any compression at all.
