I'm currently setting up Carbon Copy Cloner to create a backup clone of my SSD. I'd like to be able to store the cloned drive's Filevault 2 password in the keychain so CCC can access it to automatically do backups on a schedule. However, I don't want to store my administrator password in the keychain. (I've heard of a few exploits that allowed malware to access stored passwords).
Is there a way to set up a separate Filevault password for the cloned drive?
I'm running a MacBook 8,1 with El Capitain 10.11.6.
