[Samba] vfs_shadow_copy2 with snapprefix & delimiter options
Hello all,
I already successfully configured shadow copy service without a delimiter and
regex. But as soon as I try to get this to work with regex, nothing shows up on
the win client.
My config looks like this:
[global]
shadow: localtime = yes
shadow: sort = desc
shadow: format = _%FT%T
shadow: delimiter = _
shadow: snapprefix = ^\(monthly\)\{0,1\}\(weekly\)\{0,1\}\(daily\)\{0,1\}$
[someshare]
path = /mnt/share/User
hide dot files = No
follow symlinks = Yes
wide links = Yes
vfs objects = shadow_copy2
shadow: mountpoint = /mnt/share
shadow: snapdir = .zfs/snapshot
shadow: snapsharepath = User
The content of snapshot folder:
root:/tmp# ll /mnt/share/.zfs/snapshot/
drwxrwxrwx 2 root root 2 Aug 15 06:25 .
drwxrwxrwx 1 root root 0 Aug 7 17:17 ..

drwxrwxrwx 1 root root 0 Aug 14 12:01 weekly_2018-08-12T06:47:01
As I already told, if I use the same setup without delimiter/snapprefix and a
fixed daily/weekly/monthly format string, then it is working:
shadow: format = weekly_%FT%T
Now at this point I have no clue if its really a config failure, or a bug. Log
says its successfully parsing the snapshots:

And the windows client ends up with an empty list.
Samba version I tried so far: 4.8.2+dfsg-2 (Debian testing) and current master
of the git repository (Debian patches applied).
Hope someone has an idea what could be wrong here.
Thanks already in advance.

[Samba] vfs_shadow_copy2 with snapprefix & delimiter options
Hi,
I made some progress in the meantime.. If I change the times to UTC/GMT
(localtime = no) then it is working. Does this make sense?
If thats really how it should work, then docs needs to be updated, please.
BR.
