It does depend on how much you have to recover. I have clients whose data sets take weeks to months to copy over multi gigabit links.
Not too long ago I had to move a database to a new server. A couple of TBs needed to be moved. Both machines were part of the same network but it still took the better part of a week to copy the data to the new box and get it up and running with the copied data.
They did have a verify step in the process where they read the data after it was written but they only verified that the checksums matched the data. Fortunately this was found by a customer and none of the financial institutions involved had a bad day.
Lucky that someone noticed in time to correct the issue. I wonder how a customer was the one to notice it rather than the people doing the data recovery. -- Cheers!
