Hi, I had a problem with my Time Capsule, so disconnected my USB backup drive from the TC to backup over USB and not WiFi. Time Machine did not automatically back up, so I went and removed the two drives in Time Machine settings. Then I added the USB drive, but it did not seem to recognize there was already a backup there. It asked me to create an encryption password again. It's currently "preparing backup" again and was "encrypting drive" a few moments ago. Is this working right? How can I make sure it will resume backing up to the same series of backup created before? Thanks.
