Description: Limitation of protecting data exported to a share on an NVFR agent.

Versions: all

Symptoms:
It is not possible to set up protection for files/dir on a share via the machine they have been exported to as opposed to the machine exporting the data (where the data actually resides).

NVFR uses write interrupts on the disk level to check for write changes being made to data.
This means that the data being protected has to be selected from the machine where the disk is local, whether this is the local machine or if the disk is exported to the agent via FC or iSCSI so as to be seen as local. It is not possible to protect data exported to a normal network share via the machine it's been exported to.
