I recently bought some more LTO2 tapes for our nightly backups, however the new tapes do not hold more than around 197-202gb.
The normal tapes I am currently using are TDK tapes, and are backing up about 230gig at a compression ratio of 1.33. So it seems the drive, Arcserve and compression is all working good.
I recently bought some FujiFilm tapes and running the exact same nightly backup job, the job stops at about 197gb and Arcserve requests the next tape.
I assumed it was the brand of tape so I bought some Sony tapes, but these also stopped at about 201gb.
Thinking that maybe this drive has some sort of relationship with TDK tapes, I bought a new box of them, and these new TDK tapes stop at about 203gb.
Ive formatted the tapes as normal, compression is "on" and the block size is the same on all the tapes.
Have I missed something simple here ?
