[Samba] ZFS and vfs_shadow_copy2

[Andrea Venturoli]

Hello.

I'm trying the above combination (on FreeBSD).

Relevant part of my smb.conf is:

         vfs objects=full_audit shadow_copy2
         shadow:sort = desc
         shadow:format=-%Y%m%d%H%M%S
         shadow:delimiter=-
         shadow:snapprefix=auto_zroot
         shadow:localtime=yes
         shadow:snapdir=.zfs/snapshot


Seems like it's working, but when using "Previous versions" on Windows 
10 I only see a few snapshots, not all.

E.g., I have:
>  # ls /shares/.zfs/snapshot/
> auto_zroot-20210301002800       auto_zroot-20211101002800       auto_zroot-20220211010000       auto_zroot-20220216170000       auto_zroot-20220217120000
> auto_zroot-20210401002800       auto_zroot-20211201002800       auto_zroot-20220212020000       auto_zroot-20220216180000       auto_zroot-20220217130000
> auto_zroot-20210501002800       auto_zroot-20211229090000       auto_zroot-20220213100000       auto_zroot-20220216190000       auto_zroot-20220217140000
> auto_zroot-20210601002800       auto_zroot-20220120090000       auto_zroot-20220214090000       auto_zroot-20220216200000       auto_zroot-20220217150000
> auto_zroot-20210701002800       auto_zroot-20220127080000       auto_zroot-20220215080000       auto_zroot-20220217080000
> auto_zroot-20210801002800       auto_zroot-20220128090000       auto_zroot-20220216080000       auto_zroot-20220217090000
> auto_zroot-20210901002800       auto_zroot-20220203090000       auto_zroot-20220216150000       auto_zroot-20220217100000
> auto_zroot-20211001002800       auto_zroot-20220210080000       auto_zroot-20220216160000       auto_zroot-20220217110000

But on Windows I only see "Today", with the last 8 snapshots.

Another example: I have
> auto_zroot-20210301002800       auto_zroot-20210801002800       auto_zroot-20211201002800       auto_zroot-20211220000700       auto_zroot-20220112170000
> auto_zroot-20210401002800       auto_zroot-20210802180000       auto_zroot-20211206140000       auto_zroot-20211220090000
> auto_zroot-20210408150000       auto_zroot-20210901002800       auto_zroot-20211207000700       auto_zroot-20211220110000
> auto_zroot-20210511100000       auto_zroot-20211001002800       auto_zroot-20211207170000       auto_zroot-20220111170000
> auto_zroot-20210608150000       auto_zroot-20211101002800       auto_zroot-20211219001400       auto_zroot-20220112160000

But Windows will only show "Last month" with the last two snapshots 
(which actually belong to the last day I have snapshots for, while the 
day before is excluded, in spite of being from "last month" too).



Is this something to check Samba side or Windows side?

  bye & Thanks
