I never used shadow_copy2 VFS module... the rsync snapshots are in a nfs
share. I have mounted it on /home/shares-snapshots. The format I use is
the default value of shadow format value ("@GMT-%Y.%m.%d-%H.%M.%S").
This is the content:
$ ls /home/shares-snapshots/

for each hourly snapshot I have a log.gz file and a symbolic link named
latest that point to the latest snapshot. This structure should be
compatible is'nt it?
So I have added to the smb.conf share section something like:
vfs objects = shadow_copy2
shadow:snapdir = /home/shares-snapshots
shadow:sort = desc
# shadow:format = @GMT-%Y.%m.%d-%H.%M.%S
I haven't set the shadow:delimiter and shadow:snapprefix I haven't
understand how to set them... any way are not mandatory, aren't they?
Well, I have reload samba but from windows in the file properties no
versions are available... what I wrong?
:(
