RN314, snapshots do no start on one home share, but on others...
Hi there, I have a strange issue with the snapshots on one home folder. There the snapshots do not start, allthough a snapshot folder is present. In all other folders and shares on the NAS there is ...
Did you ever have ssh enabled? If so, it is possible that /home/Ulrike was created with ssh?
I think this could also have happened if the home folders were restored with a backup before the user ever accessed the NAS with file explorer or finder.
One option is to copy off the files, then delete the user account and the folder /home/Ulrike. Then recreate the user account, and access the NAS with that person's credentials. That should re-create the share. Then copy back the folder contents.
Note that part of the plan is that you must log into the server using that user's credentials before you restore the backup. That's because the NAS creates a share (btrfs sub-volume) for each user, not just a folder.
Alternately, from SSH, you can use mkhomedir_helper <username>.to create it..
I added the user share, logged in with the user credentials and the home-folder was created. I also added the access to the snapshots for the user and a snapshot folder appeared.
Then I copied back the files and activated the change of the owner properties of the files to the owner of the home share. With that, also a snapshot folder was copied back and the owner of this folder was changed to the user and owner of the home share.
Nothing further happened up to now.
Is there an easy way to check if the snapshots start working..? Currently I have smart weekly snapshots. I could set to hourly snapshots, but there might be a smarter way... Thanks!
Since snapshots are also subvolumes, I doubt you've gptten what you think you have. Your "snapshots" are likely full copies of the snapshot contents, not just mostly pointers to the unchanged data, And I have no idea how that is going to affect taking real snapshots.
AFAIK, there is no way to backup and restore or transfer a set of snapshots for a share except via ReadyDR, which still doesn't allow you to restore a share with it's snapshots intact.. It seems to be a BTRFS limitation, as I have looked outside of the Netgear GUI for a method and came up with nothing.

I think that was a misunderstanding. I only copied the empty snapshot-folder back, not including any snapshot, as this did not work anyhow before.
Some minutes ago I checked with hourly snapshot and there was one snaphsot established for the newly installed home share! I think it is working now properly. Thank you all for your support here.
BTW: in the mean time I noticed the possibility of manual snapshots for non-home-shares, but not for home shares...
OK, so long as you are getting valid new snapshots, I think all is well. What I explained is probably why it didn't work to copy them back. That's better than it seeming to work and not being what you really wanted.
