Hi Chris, Try deleting mysql_201708090830/ snapshot on the destination. And resend but this time do a full send of that snapshot, don't use -p. I wonder if a full send, rather than incremental makes a difference. Follow it up with the rsync command to compare origin and destination. Yes, It's different.
