I really searched a lot (in old forum, reddit and here) but didn’t find any solution:
I setup Truenas Core (TrueNAS-13.0-U6.1) in a AD environment, created several datasets (using template),
created SMB-shares in a subfolder under the dataset, but when trying to access the snapshots using windows explorer /var/log/samba4/log.smbd shows:
As long as I don‘t find a solution for that issue, truenas is working as a backup/replica target here. If somehow I‘ll solve how to adjust the appropriate rights for the snapshots, I‘ll post it here.
Snapshots happen at the dataset level therefore sharing out a directory within that dataset may not give you access to those snapshots as they are happening a layer above (albeit recursive). I can’t confirm this as I have never tried what you are doing but what I can say is that when you share out a dataset then snapshots and previous versions work great. Perhaps give that a try and see.
