home/user share snapshots

Using OS 6.5.1, the process for enabling snapshot protection for user home shares is extremely non-intuitive (assuming I've finally got it right.)

This is a fresh installation on brand new drives...  The device was upgraded to 6.5.1 before I pulled the old drives and put the new ones in.  (It might matter that my RN516 is attached to ADS.)

First you have to go to Accounts -> "Default user", and turn on protection for "home folder."  No, it's not turned on yet.  Now you have to go to shares, and hit the gear icon on the far right of the "home folders" share, select 'settings' and choose the "Snapshot Schedule" page.  From here, you set up the schedule (which is apparently shared by all user folders.)

Wait, it's STILL not working!  Hit that gear icon again, back into settings, and this time go to "snapshot access."  It doesn't matter that "snapshot access" every other place in the UI refers to making snapshots available as seperate shares.  Here, it's also used to actually turn on the snapshots for each user.  So, search for your user, and turn on the "protection" checkbox.  (You don't need to enable snapshot access, we just needed the page to turn the silly thing on.)

And now.. it STILL doesn't work.  Out of curiousity, I also turned on "allow snapshot access" for the user, and it pointed to a folder that DOESN'T EXIST on the NAS.  It claims my snapshots will be in "/home/MYDOMAIN/garyd9/snapshot" when the user folder is actually "/home/mydomain/garyd9"  (notice the case difference in the domain.)  

I wonder if THAT is the problem.  It wouldn't surprise me, as I've had many other problems with ReadyNAS devices on ADS and the NAS getting confused between MYDOMAIN and mydomain all the time.  

Trying to troubleshoot this, I also dropped into ssh and found no snapper job listed for the home share with "snapper list-configs", and "btrfs subv list /data | grep garyd9" only shows my normal home share and my user timemachine subvolume.  Nothing more.

Any suggestions?  Netgear?
