VDP and the Proxies with Hotadd!

The ports required for the VDP proxies are similar as the VDP appliance.   The proxies need access to the vCenter SDK on port 443.   The proxies also need access to the ESXi hosts they are doing the backup on port 902,443 and port 80.  

In the case with strict firewall settings or NDB is just too slow the best action will be to modify the proxy_selection_algorithm from hot_add_preferred to hot_add_only in the /usr/local/avamar/var/mc/server_data/prefs/mcserver.xml file.
Login to VDP as root and run:
 
cp /usr/local/avamar/var/mc/server_data/prefs/mcserver.xml /usr/local/avamar/var/mc/server_data/prefs/x-mcserver.xml-backup
vi /usr/local/avamar/var/mc/server_data/prefs/mcserver.xml
 
Locate and modify the flag t be:
Old:        <entry key=”proxy_selection_algorithm” value=”hot_add_preferred” />
New:      <entry key=”proxy_selection_algorithm” value=”hot_add_only” />
 
Restart the MCS service:
dpnctl stop mcs
dpnctl start mcs
dpnctl start sched
 
This change really does the trick and will force the proxy selection for the backup jobs based on their hotadd capabilities with the VM to be backed up.
