Hi,Hi,Whats your NBU version, Master,Media and Client?Is this restore working before?There are some requirements to enable GRT, did you already check this TN?https://www.veritas.com/support/en_US/article.000068163 --&gt; Everything you need to know to get Exchange Granular backups to work&nbsp;Regards,&nbsp;Thiago Ribeiro

Have you checked compatibility before Exch was upgraded?
CU15 is not mentioned in 7.6 DB SCL (not sure if you know that 7.6.x ran out of support in Feb 2017)
7.7.x DB SCL says CU15 is supported as from NBU 7.7.3.
NBU 7.0 - 7.6 DB and Application Agent CL: http://www.veritas.com/docs/000006088NBU 7.7 DB and Application Agent CL: http://www.veritas.com/docs/000025230

Hi All,The issue has been fixed. It was due to&nbsp;NFS client service in one mailbox server which is not started normally.Also we have diffrent version of Client Access server configured in backloop which we removed.Thanks All for your advice,comments and supportRegardsAshraf&nbsp;&nbsp;
