That depends. Let's consider two extreme cases:
    (A) The machine being backed up is very small, but the backup is being done 
over a 56 Kb/s dialup connection and it takes 3 days to send the data for that 
initial, complete backup.
    (B) There are nearly a billion files totalling nearly 900 terabytes, and 
just writing that much data to a disk takes 3 days.

For case (A) the regression on the server would be quite fast. For case (B) it 
could take more than the 3 days it took to write the backup originally (and 
that could be true even for regressing a small incremental backup on that huge 
archive).
