<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>
<refsection>

are listed below.</para>

the commands available in bbackupquery. Use the form <literal>help
command</literal>, to get help on a specific command.</para>
</listitem>
<listitem>
<para><literal>quit</literal></para>
<para>End the session with the store server, and quit
<literal>bbackupquery</literal>.</para>
</listitem>
<listitem>
<para><literal>cd [options] <directory-name></literal></para>
<para>Change directory. Options:</para>
<itemizedlist>
<listitem>
<para><literal>-d</literal> -- consider deleted directories for
traversal</para>
</listitem>
<listitem>
<para><literal>-o</literal> -- consider old versions of
directories for traversal. This option should never be useful in
a correctly formed store.</para>
</listitem>
</itemizedlist>
</listitem>
<listitem>
<para><literal>lcd <local-directory-name></literal></para>
<para>Change directory on the client machine. To list the contents
of the local directory, type <literal>sh ls</literal> (on unix-like
machines). TODO: Does <literal>sh dir</literal> work on
Windows?</para>
</listitem>
<listitem>
<para><literal>list [options] [directory-name]</literal></para>
<para>The <literal>list</literal> (or its synonym
<literal>ls</literal>) command lists the content of the current, or
specified, directory. The options are as follows:</para>
<itemizedlist>
<listitem>
<para><literal>-r</literal> -- recursively list all files</para>
</listitem>
<listitem>
<para><literal>-d</literal> -- list deleted files and
directories</para>

</listitem>
<listitem>
<para><literal>-F</literal> -- don't display flags</para>
</listitem>
<listitem>
<para><literal>-t</literal> -- show file modification time (and
attr mod time, if the object has attributes.</para>
</listitem>
<listitem>
<para><literal>-s</literal> -- show file size in blocks used on
server. Note that this is only a very approximate indication of
local file size.</para>
</listitem>
</itemizedlist>
</listitem>
<listitem>
<para><literal>ls [options] [directory-name]</literal></para>
<para>Synonym for <literal>list</literal>.</para>
</listitem>
<listitem>
<para><literal><literal>pwd</literal></literal></para>
<para>Print current directory, always relative to the backup store
root.</para>
</listitem>
<listitem>
<para><literal>sh <shell command></literal></para>
<para>Everything after the sh is passed to a shell and run. All
output from the command is displayed in the client.</para>
<para>Example: to list the contents of the current directory on the
client machine type <literal>sh ls</literal>.</para>
</listitem>
<listitem>
<para><literal>compare -a</literal></para>
<para><literal>compare -l <location-name></literal></para>
<para><literal>compare <store-dir-name>
<local-dir-name></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>-a</literal> -- compare all locations. </para>
</listitem>
<listitem>
<para><literal>-l</literal> -- compare one backup location as
specified in the configuration file. This compares one of the
top level store directories.</para>
</listitem>
<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>
<para>1 -- no differences were found</para>
</listitem>
<listitem>
<para>2 -- differences were found</para>
</listitem>

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>
</listitem>
<listitem>
<para><literal>getobject <object-id>
<local-filename></literal></para>
<para>Gets the object specified by the object id (in hex) and stores
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>
</listitem>
<listitem>
<para><literal>restore [-d] <directory-name>
<local-directory-name></literal></para>
<para><literal>restore -r</literal></para>

<itemizedlist>
<listitem>
<para><literal>-d</literal> -- restore a deleted
directory</para>
</listitem>
<listitem>
<para><literal>-r</literal> -- resume an interrupted

</listitem>
<listitem>
<para>usage</para>
<para>Show space used on the server for this account. Display
fields:</para>
<itemizedlist>

files</para>
</listitem>
<listitem>
<para><literal>Directories</literal>: Space used by the
directory structure</para>
</listitem>
</itemizedlist>
<para>When Used exceeds the soft limit, the server will start to
remove old and deleted files until the usage drops below the soft
limit. After a while, you should expect to see the usage stay at
just below the soft limit. You only need more space if the space
used by old and deleted files is near zero.</para>
