<para>The <command>vfs_shadow_copy</command> VFS module functionality

<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>

<title>CAVEATS</title>
|
|
|
|
<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>
