+
+    <para>
+      Now that the essential tools has been created, its time to think about
+      a backup. When every check has passed successfully in the previously 
+      built packages, your temporary tools are in a good state and might be
+      backed up for later reuse. In case of fatal failures in the subsequent
+      sections, it often turns out that removing everything and start over
+      (more carefully) is the best option to recover. Unfortunatly, all the
+      temporary tools will be removed, too. To avoid extra time to redo
+      something which has been built successfully, make sure you have at least
+      600 MB free disk space (the source tarballs will be included in the
+      backup archive) in the home directory of user 
+      <systemitem class="username">lfs</systemitem> and prepare a backup:
+    </para>
+
+<screen role="nodump"><userinput>cd $LFS &amp;&amp;
+tar -cJpf $HOME/temp-tools.tar.xz .
+</userinput></screen>
+
+    <para>
+      In case you have to start over as some mistakes has been made, you can
+      use this backup to restore the temporary tools and save some time on
+      the way to recover. Since the sources are located under 
+      <filename class="directory">$LFS</filename>, they are included in the
+      backup archive as well, so you need not to download them again. After
+      checking that <filename class="directory">$LFS</filename> is set proper,
+      restore the backup by executing the following commands:
+    </para>
+
+<screen role="nodump"><userinput>cd $LFS &amp;&amp;
+rm -rf ./* &amp;&amp;
+tar -xpf $HOME/temp-tools.tar.xz
+</userinput></screen>
+
+    <para>
+      Again, double check that the environment has been setup proper and
+      continue building the rest of the system.
