<title>DESCRIPTION</title>
<para>This VFS module is part of the
<citerefentry><refentrytitle>samba</refentrytitle>
<manvolnum>8</manvolnum></citerefentry> suite.</para>
<para>
The <command>vfs_snapper</command> VFS module exposes snapshots
managed by snapper for use by Samba. This provides the ability
for remote SMB clients to access shadow-copies via Windows
Explorer using the "previous versions" dialog.
</para>
<para>
This module is stackable.
</para>
</refsect1>
<refsect1>
<title>CONFIGURATION</title>
<para>
The underlying share path must have a corresponding snapper
configuration file. The snapshot directory tree must allow
access for relavent users.
</para>
<programlisting>
<smbconfsection name="[share]"/>
<smbconfoption name="vfs objects">snapper</smbconfoption>
</programlisting>

<title>PERMISSIONS</title>
<para>
Snapper stores snapshots under a .snapshots subdirectory. This
directory must permit traversal for any users wishing to access
snapshots via the Windows Explorer previous versions dialog.
By default, traversal is forbidden for all non-root users.
Additionally, users must be granted permission to list snapshots
managed by snapper, via snapper's ALLOW_USERS or ALLOW_GROUPS
options. Snapper can grant these users and groups .snapshots
traversal access automatically via the SYNC_ACL option.
</para>

<title>VERSION</title>
<para>
This man page is correct for version 4.2.0 of the Samba suite.
</para>
</refsect1>
<refsect1>
<title>AUTHOR</title>
<para>The original Samba software and related utilities
were created by Andrew Tridgell. Samba is now developed
by the Samba Team as an Open Source project similar
to the way the Linux kernel is developed.</para>
