configuring Exchange 2010 public folder backup

Hello All,

I am configuring exchange 2010 backup for the first time . As a start, i am trying to configure public folder backup and am struggling with that . I am new to this module and I must have missed out something very basic here. Please note, due to some legacy servers on the production, i couldn't upgrade networker server to its latest version but as per the EMC , following version of networker server is compatible with NMM3.0.1.

Any inputs to resolve this issue is greatly appreciated.  Thanks in advance.

Details are below:

Networker Server software version is : 7.6.3

Networker Client software version : 8.1.3 ( OS backup runs fine)

Nmm version: 3.0.1

Exchange 2010 and running on windows server 2008 .

Saveset details :  APPLICATIONS:\Microsoft Exchange 2010\PFxxx

Backup command :  nsrsnap_vss_save.exe
