Hi, OP here. Just an update. Last night I did the usual copy from the primary backup drive to the secondary backup drive, except I did it using rsync --delete instead of rsync --delete-after. This time, it took 73 minutes. The previous time it took 131 minutes. So it did go significantly quicker. And "seemed" to go okay. Thank you to all who have weighed in on this topic!
