Solution: 

Perform the following changes in the registry on Both Source & Destination Recovery Point server
1. Take a backup of the registry
2. Create New key  'GDDClient' under Path- HKEY_LOCAL_MACHINE\SOFTWARE\Arcserve\Unified Data 
    Protection\Engine
3. Create a 32 bit DWORD Value 'ClientandServerTimeoutInSeconds' under it & set value to 900 decimal.
4. Screen shot for reference.
