I had vxaTool look at my tape already. This is what I used to format my tape to VXA-2 format. And I did a full write test with btape earlier today. Here's what have been returned (following a bunch of '+'): Write failed at block 1110671. stat=-1 ERR=No space left on device btape: btape.c:410 Volume bytes=71.65 GB. Write rate = 5.587 MB/s btape: btape.c:608 Wrote 1 EOF to "VXA-2" (/dev/nst0) So, since btape comes from Bacula, I assume that, in some way, Bacula should be able to write to my VXA-2 tape a more or less 80GB of data. So what's the difference between bacula-sd's way of accessing the tape and btape's way? I'll try to force the maximum size of the tape in the config but I would have to put it over 80GB limit if I only want the hardware compression to be useful. Not sure of the results, though.
