samba - Apr 2018 - Shadow_copy2 and exposing multiple levels of snapshots

Hello Group,

Looking for a little assistance on this as I have been unsuccessful is
getting the shadow: snapprefix, shadow:delimiter and shadow:format to work
as I expect.

I have no issue with getting previous versions in Windows to show me either
hourly, daily or weekly, etc snapshots as previous versions.  But I owuld
like to be able to expose all.

The shadow:snapprefix, etc seems to be the way to do it, but I am unable to
get it to work.
When I setup the prefix, etc, I get know previous versions at all.

My setup in Smb.conf is below, and my directories are named as follows:


shadow:snapprefix ^\(zfs-auto-snap_dai\)\{0,1\}\(zfs-auto-snap_hour\)\{0,1\}$
shadow:delimiter = ly-
shadow:format = ly-%Y-%m-%d-%H%M


Directories :


zfs-auto-snap_daily-2018-01-01-1235
zfs-auto-snap_daily-2018-03-15-1135
zfs-auto-snap_daily-2018-03-29-1135
zfs-auto-snap_hourly-2018-04-03-1817
zfs-auto-snap_hourly-2018-04-04-0817
zfs-auto-snap_weekly-2018-01-17-1240


Etc, etc, etc

When I do something like : shadow: format zfs-auto-snap_hourly-%Y-%m-%d-%H%M

in the smb.conf, without the prefix, etc, there is no issues.  I see the
hourlys appear in my previous versions.

I am using the latest version of Samba, and Ubuntu 16.04


Any help would be appreciated.
Regards
