I have a 1 TB internal drive (with APFS file system and FileVault enabled) I want to backup using Time Machine to an external USB hard drive. I want the backup itself encrypted so no one who has the hard drive can read/restore its content without a password.
Should I format the Time Machine partition as APFS or APFS (encrypted)? Should I select "Encrypt backups" option when creating the Time Machine or should I even do both?
I called Apple and they told me to do both but the call center agent did not really make the impression that he knows for sure.
