+ <title>CONFIGURATION</title>
+
+ <para><command>vfs_shadow_copy</command> relies on a filesystem
+ snapshot implementation. Many common filesystems have native
+ support for this.
+ </para>
+
+ <para>Filesystem snapshots must be mounted on
+ specially named directories in order to be recognized by
+ <command>vfs_shadow_copy</command>. The snapshot mount points must
+ be immediate children of a the directory being shared.</para>
+
+ <para>The snapshot naming convention is @GMT-YYYY.MM.DD-hh.mm.ss,
+ where:
+ <itemizedlist>
+ <listitem><para><command>YYYY</command> is the 4 digit year</para></listitem>
+ <listitem><para><command>MM</command> is the 2 digit month</para></listitem>
+ <listitem><para><command>DD</command> is the 2 digit day</para></listitem>
+ <listitem><para><command>hh</command> is the 2 digit hour</para></listitem>
+ <listitem><para><command>mm</command> is the 2 digit minute</para></listitem>
+ <listitem><para><command>ss</command> is the 2 digit second.</para></listitem>
+ </itemizedlist>
+ </para>
+
+ <para>The <command>vfs_shadow_copy</command> snapshot naming convention can be produced with the following
+ <citerefentry><refentrytitle>date</refentrytitle>
+ <manvolnum>1</manvolnum></citerefentry> command:
+ <programlisting>

+
+ <para>This is not a backup, archival, or version control solution.
+ </para>
+
+ <para>With Samba or Windows servers,
+ <command>vfs_shadow_copy</command> is designed to be an end-user
+ tool only. It does not replace or enhance your backup and
+ archival solutions and should in no way be considered as
+ such. Additionally, if you need version control, implement a
+ version control system.</para>
