writing that they are correct for version x is not always precise. But we're working on that also :-) Signed-off-by: Bjoern Jacke <bjacke@samba.org> Reviewed-by: Andrew Bartlett <abartlet@samba.org> Reviewed-by: Garming Sam <garming@catalyst.net.nz>

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>
|
|
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.

<title>CONFIGURATION</title>

|
|
<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
|

server must be configured in the [global] section:

<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>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>
