My question is about whether a DFS/SMB ZFS should be backed up at all

you have an idea of what the recovery time would be if you had to do it?
Can you allocate an empty zFS mounted at a different mount point an tell
TSM to restore it at a different starting node, something like
/test_restore/.... etc?
ISTR you can restore a file or directory tree to the original location
(the default) or to an alternate location of your choosing. I will run a
test to see how long a full volume restore takes. Good idea, Mark!
I suspect such a restore will be orders of magnitude slower than a
full-volume HSM restore of the ZFS since there are literally tens of
thousands of individual files to be restored. But maybe some
optimizations occur when you restore whole directories. I'll let you know...
