+ <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>
+ Snapshots can also be created and remove remotely, using the
+ File Server Remote VSS Protocol (FSRVP). Snapshot creation and
+ deletion requests are forwarded to snapper via DBus.
+ </para>

+ <para>
+ This module is stackable.

+
+ <para>
+ The underlying share path must have a corresponding snapper
+ configuration file. The snapshot directory tree must allow
+ access for relevant users.

+ For remote snapshot creation and deletion, Samba's FSRVP

+ <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>
+ <para>
+ Remote snapshot creation and deletion is only permitted by Samba
+ for Active Directory administrators, backup operators, or users
+ explicitly granted SeBackupPrivilege. Snapper must also permit
+ creation and deletion for the appropriate user, via snapper's
+ ALLOW_USERS or ALLOW_GROUPS options.
+ </para>
+ <para>
+ The DiskShadow.exe FSRVP client initially authenticates as the
+ Active Directory computer account. This account must therefore
+ be granted the same permissions as the user account issuing the
+ snapshot creation and deletion requests.
+ </para>

+ <para>The original Samba software and related utilities
