to estimate the amount of time the initial fs_copy takes.
Select the right formula to calculate the time
(0.8 = Network overhead. The assumption is the PFS is full.)
A. Full fs_copy time (h) = PFS size (GB) * Update ratio (%) / 1024 / 100 /24 / 3600 / 0.8
B. Full fs_copy time (h) = PFS size (GB) * Update ratio (%) / 1024 / 100 /24 / (3600 * 0.8)
C. Full fs_copy time (h) = PFS size (GB) / Network bandwidth (MB/sec) * 1024 / (3600 * 0.8)
D. Full fs_copy time (h) = PFS size (MB) / Network bandwidth (MB/sec) * 1024 / (3600 * 0.8)
