Presumably more than just broker and cluster configs and their metadata since that's relatively straightforward... Usually the question is what data, effects and business processes do you want to be able to fail over to a geographically separated site, and what sorts of guarantees do you want for the failover. This naturally affects the design of your application and its deployment fairly intimately.<br><br>If you feel comfortable talking more about what you want from your scenario we can probably make some suggestions based on things we've seen done...<br><br>Best regards,<br>Jerry<br><br><o:p></o:p></p><div><p class=MsoNormal>On Fri, Aug 3, 2012 at 11:29 AM, Ruben Rotteveel <<a href="mailto:ruben@fiadmin.com" target="_blank">ruben@fiadmin.com</a>> wrote:<o:p></o:p></p><div><div><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'>Hi All,<o:p></o:p></p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'> <o:p></o:p></p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'>What is your recommendation for how to mirror a rabbitmq installation in a DR site?<o:p></o:p></p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'> <o:p></o:p></p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'>Thanks,<o:p></o:p></p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'><span style='font-size:8.0pt;font-family:"Meiryo UI","sans-serif";color:#1F497D'>Ruben Rotteveel</span><o:p></o:p></p></div></div><p class=MsoNormal style='margin-bottom:12.0pt'><br>_______________________________________________<br>rabbitmq-discuss mailing list<br><a href="mailto:rabbitmq-discuss@lists.rabbitmq.com">rabbitmq-discuss@lists.rabbitmq.com</a><br><a href="https://lists.rabbitmq.com/cgi-bin/mailman/listinfo/rabbitmq-discuss" target="_blank">https://lists.rabbitmq.com/cgi-bin/mailman/listinfo/rabbitmq-discuss</a><o:p></o:p></p></div><p class=MsoNormal><o:p> </o:p></p></div></body></html>
