ZFS snapshots by "Previous Versions" not working

[ouranos6]

Hello,

I've installed everything following your installation guide and it's working, I can access the web interface and mount the share folder onto my win11.

I've tried to see the differents versions of my same text file but not possible.

If I run

zfs list -t snapshot zfs list

I can see all the snapshots I've done.

Do you have some hints or ideas about that?

Hello,

you need to install zfs-auto-snapshot on host system. (configure it according to the following guide) Or you can create the snapshots manually and naming them correctly: test-zfs/subvol-101-disk-0@zfs-auto-snap_frequent-2023-10-30-0830 etc.

zmb-member are zmb-standalone are preconfigured for zfs-auto-snapshot, but also works with other snapshot engines. You need to adjust the regex search filter in /etc/samba/smb.conf inside the container to match the snapshot names of the installed snapshot engine:

zamba-lxc-toolbox/src/zmb-member/install-service.sh

Line 77 in 20a158c

shadow: snapprefix = ^zfs-auto-snap_\(frequent\)\{0,1\}\(hourly\)\{0,1\}\(daily\)\{0,1\}\(weekly\)\{0,1\}\(monthly\)\{0,1\}\(backup\)\{0,1\}\(manual\)\{0,1\}

One should mention that all these funny things do not work as expected in 'zmb-standalone'. There, the configuration is stored in the registry with fancy web editor from 45drives. This editor does not work with lines starting with a dash (message Invalid option -20: unknown option). Registry tools (sudo net conf setparm global "shadow: delimiter" -20) do not work either.

Other values do not do the magic, as mentioned here and there.

The only solution I have found is to manually put this into /etc/samba/smb.conf and not in the registry.
