The TDS Group will be using a Clone of its 250GB application LUN for backup purposes. You have bound two Clone Private LUNs of 250MB each. TDS heard that Clone granularity is not a fixed value. The Group wants an estimate of the granularity for its 250GB LUN. What do you tell TDS?

A.
The granularity is around 2 MB for this size LUN and this size Clone Private LUN

B.
The granularity is around 1 MB for this size LUN and any valid Clone Private LUN

C.
The granularity is impossible to calculate without knowing the I/O profile of the application, but will be no less than 128 kB

D.
The granularity is impossible to calculate without knowing the I/O profile of the application, but will be no more than 128 kB
