- <title>DESCRIPTION</title>
-
- <para>This VFS module is part of the
- <citerefentry><refentrytitle>samba</refentrytitle>
- <manvolnum>7</manvolnum></citerefentry> suite.</para>
-
- <para>The <command>vfs_shadow_copy2</command> VFS module functionality
- that is similar to Microsoft Shadow Copy services. When setup properly,
- this module allows Microsoft Shadow Copy clients to browse
- "shadow copies" on Samba shares.
- </para>
-
- <para>This is a 2nd implementation of a shadow copy module. This
- version has the following features:</para>
- <orderedlist continuation="restarts" inheritnum="ignore" numeration="arabic">
- <listitem><para>You don't need to populate your shares with symlinks to the
- snapshots. This can be very important when you have thousands of
- shares, or use [homes].</para></listitem>
- <listitem><para>The inode number of the files is altered so it is different
- from the original. This allows the 'restore' button to work
- without a sharing violation.</para></listitem>
- </orderedlist>
-
- <para>This module is stackable.</para>

- <title>CONFIGURATION</title>
-
- <para><command>vfs_shadow_copy2</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_copy2</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_copy2</command> snapshot naming convention can be
- produced with the following <citerefentry><refentrytitle>date</refentrytitle>
- <manvolnum>1</manvolnum></citerefentry> command:
- <programlisting>
- TZ=GMT date +@GMT-%Y.%m.%d-%H.%M.%S
- </programlisting></para>

- <title>OPTIONS</title>
-
- <variablelist>
- <varlistentry>
- <term>shadow:snapdir = SNAPDIR
- </term>
- <listitem>
- <para>Path to the directory where snapshots are kept.
- </para>
- </listitem>
- </varlistentry>
-
- <varlistentry>
- <term>shadow:basedir = BASEDIR
- </term>
- <listitem>
- <para>Path to the base directory that snapshots are from.
- </para>
- </listitem>
- </varlistentry>
-
- <varlistentry>
- <term>shadow:sort = asc/desc, or not specified for unsorted (default)
- </term>
- <listitem>
- <para>By this parameter one can specify that the shadow
- copy directories should be sorted before they are sent to the
- client. This can be beneficial as unix filesystems are usually
- not listed alphabetically sorted. If enabled, you typically
- want to specify descending order.
- </para>
- </listitem>
- </varlistentry>
-
- <varlistentry>
- <term>shadow:localtime = yes/no
- </term>
- <listitem>
- <para>This is an optional parameter that indicates whether the
- snapshot names are in UTC/GMT or in local time. By default
- UTC is expected.
- </para>
- </listitem>
- </varlistentry>
-
- <varlistentry>
- <term>shadow:format = format specification for snapshot names
- </term>
- <listitem>
- <para>This is an optional parameter that specifies the format
- specification for the naming of snapshots. The format must
- be compatible with the conversion specifications recognized
- by str[fp]time. The default value is "@GMT-%Y.%m.%d-%H.%M.%S".
- </para>
- </listitem>
- </varlistentry>
-
- <varlistentry>
- <term>shadow:fixinodes = yes/no
- </term>
- <listitem>
- <para>If you enable <command moreinfo="none">shadow:fixinodes
- </command> then this module will modify the apparent inode
- number of files in the snapshot directories using a hash of the
- files path. This is needed for snapshot systems where the
- snapshots have the same device:inode number as the original
- files (such as happens with GPFS snapshots). If you don't set
- this option then the 'restore' button in the shadow copy UI
- will fail with a sharing violation.
- </para>

-
- <para>This is not a backup, archival, or version control solution.
- </para>
-
- <para>With Samba or Windows servers,
- <command>vfs_shadow_copy2</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>

- <para>The original Samba software and related utilities
