Hi Pavan and all:
We have committed the RHV support for next release of NetBackup. It would help if we can have a weekly/bi weekly call for next 2 months. If there are no topics then we can cancel the call.
Please let us know if this is fine and we can send a calendar invite.
+ Renee
Thanks
Navin

We could achieve this if this only if it was a first snapshot when the actual size is same as the provisional size and not for interleaved snapshots.
