As currently implemented, you are correct. A stage or a clone or multiple recovers may be performed on the AFTD. If a stage is running,

clones and recovers have to wait for it to complete.

Hmmm... VTLs don't have that problem. ;)  OK, they sort of do.  You
can't restore from a tape that's currently being cloned, but you can
restore from other tapes.  It looks like the entire AFTD is held up
while cloning/staging is going on.

Quite true... but I can do a clone/stage/recover while I'm writing backups to the AFTD. You can't do that with a tape (virtual or real).

Another AFTD limitation that I've heard of, but haven't verified is that
the RO side of the AFTD is counted in some way against your device
count.  I don't know the details and haven't verified, but there are
some per server device limits that certain versions of NW have, and my
understanding is that the AFTD is counted as two against those numbers.
Can anyone verify that this is true or false?

True. But it hasn't been a problem for us and we've used AFTDs with 7.2 and 7.3 (Our NetWorker install was at 7.2.2 when I inherited it, so I can't speak about anything prior to that).
