It does make a difference! First only when accessing the directory on 
the server itself as a non priviledged AD user. Without acl I can enter 
the .snaps dir, with acl I can not.

Using Windows I wasn't able to access the privious version, but 
remembering Alexanders comment I could fix that aswell!

So my share looks like this now:
[projects]
         path = /srv/glvol_samba/admin/projects
         comment = ARC Projekte
         guest ok = no
         read only = no
         shadow:snapdir = /srv/glvol_samba/admin/projects/.snaps
         shadow:basedir = /srv/glvol_samba/admin/projects
         shadow:sort = desc
         vfs objects = acl_xattr shadow_copy2 glusterfs_fuse
         shadow:format = snap_GMT-%Y.%m.%d-%H.%M.%S



And my mounting unit looks like this:

[Unit]
Description=Data Dir
After=network.target
Requires=network-online.target

[Mount]
What=B741:/glvol_samba
Where=/srv/glvol_samba
Type=glusterfs
Options=defaults,_netdev,negative-timeout=10,attribute-timeout=30,fopen-keep-cache,direct-io-mode=enable

[Install]
WantedBy=multi-user.target



Now I have to test if the missing acl options has any influence on the 
windows acls.

Best regards and a big big Thank you!

Sebastian
