Back up not encrypted: Time Machine is backing up an encrypted disk to an unencrypted disk

This is all true, but what if unencrypted backups are what I want? My external hard drive is in a very secure location, and being unable to access my backups if some encryption key was misplaced or unavailable represents a bigger risk to my data than having the drive stolen. I've been ignoring the "Backup not encrypted" message. Today I was on the road without the external disk for backup for the first time in weeks and I got "No backups for 43 days". This is very disturbing, since I installed Sierra 43 days ago. Is Sierra backup refusing to do unencrypted backups from an encrypted drive? That's not at all what the message says, or what your explanation implies.

Hi jameson. Time machine gave me the same notification, the problem is that my Mac's SSD is not encrypted. I checked in the FileVault settings.

What does that mean?

You may lose the laptop when you go out, but hopefully not the Time Capsule if you lock your house. It just a warning that it backed up the encrypted mounts which are de-encrypted. Open Time Machine and see your backups.

Same question; encrypted drive, unencrypted backups. Result - one current backup in time machine is visible even though backups seem to have been ongoing for months.
