 ====== Enable Synchronization between Shadow and Samba Passwords ======
+<WRAP info>
+The Samba-PAM password sync module has been deprecated. An alternative is to [[samba/ldap_authentication_backend|use LDAP as an authentication backend]].
+</WRAP>
 To enable the synchronization between shadow and Samba passwords install the ''libpam-smbpass'' module:

 passwd chat = *Enter\snew\s*\spassword:* %n\n *Retype\snew\s*\spassword:* %n\n *password\supdated\ssuccessfully* .
 pam password change = yes

+====== Enable Volume Shadow Copies with ZFS ======
+If the underlying filesystem supports shadow copies then Samba can be made to utilize shadow copies. On Debian, first install ''zfs-auto-snapshot'':
+<code bash>
+aptitude install zfs-auto-snapshot
+</code>
+and then enable the ''shadow_copy2'' vfs object:
+<code>
+[global]
+...
+    vfs_objects = shadow_copy2
+    shadow: snapdir = .zfs/snapshot
+    shadow: sort = desc
+    shadow: format = zfs-auto-snap_%S-%Y-%m-%d-%H%M
+    shadow:localtime = no
+</code>
+====== Performance with ZFS ======
+At the time of writing, ZFS does not have sendfile support, so make sure to disable it for a performance boost and particularly if timeouts are to be observed:
+<code>
+use sendfile = no
 </code>
