RN214 refuses to take snapshots
Hi! After factory-resetting and reinstalling my RN214 (check out https://community.netgear.com/t5/Using-your-ReadyNAS-in-Business/Admin-page-unavailable-after-cancelled-backup-job-amp-hard/m-p/21...

Manual and automatic snapshots for other shares not related to individual users worked fine. There was no issue with insufficient space (no snapshot pruning taking place) [...] So I have created a new user "test" with all default settings in the "Users" group. [...] for user "test" automatic snapshots are actually taken successfully, while at the same time, no snapshots for user "volker" are stored even though he is sharing the same schedule. As it happens to be, [X] Allow snapshot access was enabled for volker and [ ] Protection was disabled, user "test" had it the other way round. [...]
Currently, I'm running a test with various combinations of (dis)allowing snapshot access and en-/disabling the protection feature, (de)activating bit rot protection and compression for the other shares to find out what exactly spoils the fun here.
The tests have completed. Conclusion:
If you don't activate the [X] Protection option in the Home Folders > Settings > Snapshot Access for all the users where snapshots should be taken, no schedule whatsoever is going to work. Everything else (Bit-rot-protection and compression for shares, snapshot access for individual users, the type of schedule and whether you want snapshots even if nothing changed) does not matter.
So if some Netgear dude is listening: Perhaps this critical relationship could at least be made more clear in the manual or probably even a warning displayed if the admin deviates from a setting that implicitely disables snapshots.

Alternately, you can use the command mkhomedir_helper from ssh to create each user's share instead of logging in using each user's credentials. You must still rename the current folders first, since there can be no duplicates.

I was following StephenB 's advice and all users' home folders showed up as BTRFS subvolumes. My posting covering that still seems to be in approval though. So that hopefully means all is good and snapshots should work as expected with no side effects as soon as I activate the "[X] Protection" option in the context menu.
You advice with the mkhomedir_helper script is still quite cool. I wonder how you found out about it?
It's been a while since I reset the box and restored the backup - so it could very well be that I tried all users/passwords first and then took care of the data. Lucky coincidence.
