The way in which you do this in Exchange 2010 has changes, and it’s important that when you implement such a configurationen-USTelligent Evolution Platform Developer Build (Build: 5.6.50428.7875)http://blogs.technet.com/b/timmcmic/archive/2011/10/25/exchange-2010-implementing-a-dedicated-backup-network-for-a-database-availability-group.aspx#3519096Mon, 10 Sep 2012 03:19:40 GMTd5e57398-b9ef-4490-9955-07cbb4e4a80d:3519096TIMMCMIC<p>@Neothwin:</p> <p>No - that&#39;s the purpose of this blog. &nbsp;The DAG is only designed to have IP addresses on the public / mapi network.</p> <p>TIMMCMIC</p> <div style="clear:both;"></div><img src="http://blogs.technet.com/aggbug.aspx?PostID=3519096" width="1" height="1">http://blogs.technet.com/b/timmcmic/archive/2011/10/25/exchange-2010-implementing-a-dedicated-backup-network-for-a-database-availability-group.aspx#3519088Mon, 10 Sep 2012 00:54:31 GMTd5e57398-b9ef-4490-9955-07cbb4e4a80d:3519088Neothwin<p>Is it possible to create new virtual IP for Backup network in DAG?</p> <p>Is it supported?</p> <p>regards,</p> <div style="clear:both;"></div><img src="http://blogs.technet.com/aggbug.aspx?PostID=3519088" width="1" height="1">http://blogs.technet.com/b/timmcmic/archive/2011/10/25/exchange-2010-implementing-a-dedicated-backup-network-for-a-database-availability-group.aspx#3518159Wed, 05 Sep 2012 11:08:45 GMTd5e57398-b9ef-4490-9955-07cbb4e4a80d:3518159TIMMCMIC<p>@Neothwin</p> <p>I still think you need to speak with your vendor. &nbsp;Based on my experience with netbackup (which is not depth by any means - just assisting other people with these steps) I do not think what you are proposing will be possible. &nbsp;</p> <p>TIMMCMIC</p> <div style="clear:both;"></div><img src="http://blogs.technet.com/aggbug.aspx?PostID=3518159" width="1" height="1">http://blogs.technet.com/b/timmcmic/archive/2011/10/25/exchange-2010-implementing-a-dedicated-backup-network-for-a-database-availability-group.aspx#3518131Wed, 05 Sep 2012 07:28:49 GMTd5e57398-b9ef-4490-9955-07cbb4e4a80d:3518131Neothwin<p>Thanks and appreciate your quick respond. </p> <p>We are using netbackup in our env. Adding mapi interface on backup server or routing to mapi network is not possible.</p> <p>I&#39;m thinking to use static NAT between DAG mapi IP to backup network IP. (e.g.10.0.0.100 &lt;=&gt; 10.1.1.5). So when backup server start topology discovery, it will use 10.1.1.5. Will this approach work?</p> <p>Then again, we have another challenge if the DAG mapi network is across two network, DAG name have two different mapi IPs and only one will be up at a time. :)</p> <p>rgds</p> <div style="clear:both;"></div><img src="http://blogs.technet.com/aggbug.aspx?PostID=3518131" width="1" height="1">http://blogs.technet.com/b/timmcmic/archive/2011/10/25/exchange-2010-implementing-a-dedicated-backup-network-for-a-database-availability-group.aspx#3517863Tue, 04 Sep 2012 11:39:18 GMTd5e57398-b9ef-4490-9955-07cbb4e4a80d:3517863TIMMCMIC<p>@Neothwin:</p> <p>You would have to consult with your backup vendor for this particular installation. &nbsp;You will not though be able to add an additional IP address for the DAG on the dedicated network. &nbsp;This may require that you establish access to the DAG on the MAPI network.</p> <p>TIMMCMIC</p> <div style="clear:both;"></div><img src="http://blogs.technet.com/aggbug.aspx?PostID=3517863" width="1" height="1">http://blogs.technet.com/b/timmcmic/archive/2011/10/25/exchange-2010-implementing-a-dedicated-backup-network-for-a-database-availability-group.aspx#3517781Tue, 04 Sep 2012 03:47:02 GMTd5e57398-b9ef-4490-9955-07cbb4e4a80d:3517781Neothwin<p>Thanks for the great article.</p> <p>In our env, the backup server only have backup network, no access to mapi network at all.
