samba - Mar 2016 - howto domain controller with home shares on file server

hi
i have two active domain controllers dc1 and dc2 and i have a domain
member which is a file server fs1,
my home and profile shares are on fs1 and i mount the on dc1 and dc2 for
admin purposes i.e. to create user home shares,
fs1 uses the btrfs filesystem and snapper.

this is my smb.conf on the file server

what is the best method to access user share when i logon using a
windows client,
without losing the snapshot capability from snapper.

do i,
1  add the share definition to smb.conf on the domain controllers and
remove them from the file server
2  leave the share definition in smb.conf on the file server and use the
microsoft rsat to connect clients to their home share

or is there a better way i have not thought of ?
