You can use concurrency with tape, yes. I write five concurrent jobs to 
LTO-4. (I have an autochanger, but it's only got a single LTO4 tape 
drive in it).

The bacula manual warns somewhat against using concurrent jobs with 
tape, but I've been using it for a year, every restore has been 100% 
perfect, and the restore speed is absolutely fine for my needs, it's 
pretty quick anyway.

I'm not sure about spooling as I don't use it but I understand it can 
help to increase restore speed, but as I said, I don't have a problem 
with restore speed anyway.
