I agree that's what the manual says. In my testing the smallest I could
get it down to was two. Specifying 1 acted like 2. Since this was my
sandbox and our production environment would be greater than 2 task, I
did not follow up with IBM.

Not according to the manual:
Explanation: MAXBACKUPTASKS(nn) is an optional parameter specifying the
maximum number of volume backup tasks DFSMShsm can concurrently process.
For nn, substitute a decimal number from 1 to 15 to represent the number
of volume backup tasks to be run concurrently.

I believed we saw this too. Decided the min number was two task.

Subject: [IBM-MAIN] DFHSM MAXBACKUPTASKS(1) using 2 drives
OS- z/OS 1.7 put RSU0809
DFHSM SETSYS MAXBACKUPTASKS(1) and DUPLEX BACKUP(N)
When AUTOBACKUPSTART DFHSM is allocating two tape drives. Even though
the Setsys is set to MAXBACKUPTASK (1).
Any ideas why?
Thanks, Jaime
