Thor774 macrumors regular Original poster Mar 12, 2017 #1 I am recreating my encrypted TM backup in a new external USB3 disk. Is there any noticeable difference in the performance of the backup between using a 20 characters key length and a 50 characters one? The machine is a MBP 15" 2015 model. Thanks.
