The backup can either be a conventional backup or a hot backup. <p><li>Copy the archival backup into a clean environment directory on the client. <p><li>Run catastrophic recovery on the client's new environment, as described in <a href="../../ref/transapp/recovery.html">Recovery procedures</a>. <p><li>Reconfigure and reopen the environment as a client member of the replication group. </ol> <p>If copying the backup to the client takes a long time relative to the frequency with which log files are reclaimed using the <a href="../../utility/db_archive.html">db_archive</a> utility or the <a href="../../api_c/log_archive.html">DB_ENV->log_archive</a> method, it may be necessary to suppress log reclamation until the newly restarted client has "caught up" and applied all log records generated during its downtime.</p> <p>As with any Berkeley DB application, the database environment must be in a consistent state at application startup. This is most easily assured by running recovery at startup time in one thread or process; it is harmless to do this on both clients and masters even when not strictly necessary.</p> <table width="100%"><tr><td><br></td><td align=right><a href="../rep/newsite.html"><img src="../../images/prev.gif" alt="Prev"></a><a href="../toc.html"><img src="../../images/ref.gif" alt="Ref"></a><a href="../rep/elect.html"><img src="../../images/next.gif" alt="Next"></a> </td></tr></table> <p><font size=1><a href="../../sleepycat/legal.html">Copyright (c) 1996-2003</a> <a href="http://www.sleepycat.com">Sleepycat Software, Inc.</a> - All rights reserved.</font> </body> </html>
