    <title>Description</title>

    <para><literal>bbackupquery</literal> is the main way of interacting with
    the backup store from a Box Backup client machine. It supports both
    interactive and batch modes of operation.</para>

    <para>It can be used to reviewing the status of a client machine's backup
    store, getting status from the store server. The main use is to retrieve
    files and directories when needed.</para>

    <para><literal>bbackupquery</literal> supports interactive and batch modes
    of operation. Interactive mode allows for interaction with the server much
    like an interactive FTP client.</para>

    <para>Batch mode is invoked by putting commands into the invocation of
    bbackupquery. Example:</para>

    <programlisting>bbackupquery "list home-dirs" quit</programlisting>

    <para>Note that commands that contain spaces are enclosed in double
    quotes. If the <literal>quit</literal> command is ommitted, after the
    preceding commands are completed, <literal>bbackupquery</literal> will
    enter interactive mode.</para>

    <para><emphasis role="bold">Options</emphasis></para>

    <para><emphasis>-q: Quiet. Suppresses status output while
    running.</emphasis></para>

    <para><emphasis>-c configfile: Use config file, instead of the default
    bbackupd.conf file. Can be a relative or full path.</emphasis></para>

          <para><literal>compare &lt;store-dir-name&gt;
          &lt;local-dir-name&gt;</literal></para>

          <para>Compare the current data in the store with the data on the
          disc. Please note that all the data will be downloaded from the
          store, so this can be a very lengthy process depending on the size
          of the store, and the size of the part you are comparing.</para>

          <para>Options:</para>

          <itemizedlist>

            <listitem>
              <para><literal>-c</literal> -- set return code. The return code
              is set to the following values, if <literal>quit</literal> is
              the next command. So, if another command is run after the
              <literal>compare</literal>, the return code will not refer to
              the <literal>compare</literal>. This option is very useful for
              automating compares. Return code values:</para>

              <itemizedlist>
                <listitem>

          &lt;local-filename&gt;</literal></para>

          <para>Gets a file from the store. Object is specified as the
          filename within the current directory. Local filename is optional.
          Ignores old and deleted files when searching the directory for the
          file to retrieve.</para>

          <para>To get an old or deleted file, use the <literal>-i</literal>
          option and select the object as a hex object ID (first column in
          listing). The local filename must be specified.</para>

          the raw contents in the local file specified. <emphasis
          role="bold">Note</emphasis>: This is only useful for debugging as it
          does not decode files from the stored format, which is encrypted and
          compressed.</para>

          <para><literal>restore [-d] &lt;directory-name&gt;

          <para><literal>restore -r</literal></para>

          <para>Restores a directory to the local disc. The local directory
          specified must not exist (unless a previous restore is being
          restarted). The root cannot be restored -- restore locations
          individually. </para>

          <para>Options:</para>

          <itemizedlist>
            <listitem>
              <para><literal>-d</literal> -- restore a deleted

            </listitem>
          </itemizedlist>

          <para> If a restore operation is interrupted for any reason, it can
          be restarted using the <literal>-r</literal> switch. Restore
          progress information is saved in a file at regular intervals during
          the restore operation to allow restarts.</para>

          <para>When Used exceeds the soft limit, the server will start to

          used by old and deleted files is near zero.</para>
