I have talked about VADP with hotadd in previous posts. Last month, I have completed testing on VADP with NetWorker 7.6.2.7. Turn out I should upgrade to NetWorker 7.6.3.7 because of the following two issue.
NW138379 - VADP : Save does not honor the VSS:*=off flag in Windows 2008
This issue is seen if you proxy host is Windows 2008.
Event 16, source: volsnap, Logged: 1/17/2012 6:25:51 PM
The shadow copies of volume E: were aborted because volume, which contains shadow copy storage for this shadow copy, was force dismounted
Another anonying issue is NW139877 - VADP: nsrvadp_save incorrectly reports status as success for aborted backups
I have not tried NetWorker 7.6.4. However, I have not encountered those issues after upgrading to NetWorker 7.6.3.7.
Whether virtual or physical proxy, you can consult the following page Nuts and bolts in NetBackup for VMware: Transport methods and TCP ports to decide which transport mode you plan to use. I don't prefer SAN mode even though it is the fastest option. Presenting a VMFS lun to a Windows 2008 proxy is not an option in some sites. If you want to use SAN mode, make sure to control who can login to the proxy. You don't want Windows signature written to a VMFS lun by mistake.
