The Western Digital My Passport Ultra 3TB disk, for example, works fine as a bootable device when not encrypted. Some versions of OS X have difficulty recognizing USB devices that have been encrypted with FileVault. Why can't I boot from that volume any more? I enabled encryption on my 3TB USB backup disk.
#ENCRYPTED FOLDER BACKUP PASSWORD#
#ENCRYPTED FOLDER BACKUP UPDATE#
Resetting the password while booted from the backup volume will update the encryption key for that user on the backup volume.

The encryption password(s) on the backup volume will not be automatically updated when you change the password for an account on the source volume. What happens if I change my account password on the source volume? Does the encryption password on the backup volume get updated automatically? If you erased your backup volume as encrypted in Disk Utility, then you will use the password that you specified in Disk Utility to unlock the volume.

Do not attempt to use the Recovery Key or your Apple ID account password to unlock the volume - those passwords will not unlock the volume. To unlock the volume in the future, enter the password to any of those user accounts.
#ENCRYPTED FOLDER BACKUP MAC#
When you boot your Mac from the backup volume and enable FileVault in System Preferences, you explicitly choose which user accounts will be allowed to unlock that volume. What password do I use to unlock my encrypted volume? Once you have enabled encryption on the backup volume, you can reboot from your production startup disk and the encryption process will continue in the background. Do I have to wait for encryption to complete before rebooting from my production volume? You can enable encryption in the Security & Privacy preference pane while booted from your bootable backup, or in the Finder by right-clicking on your backup volume (for a backup volume that does not have an installation of macOS). Will Carbon Copy Cloner enable encryption on my backup volume? If you want the contents of your backup volume to be encrypted, follow the procedure documented here to enable encryption. Whether your backed-up files are encrypted on the destination depends on whether encryption is enabled on the destination volume. When an application reads a file from the encrypted source volume, macOS decrypts the file on-the-fly, so the application only ever has access to the decrypted contents of the file. No, encryption occurs at a much lower level than copying files. If I back up an encrypted volume to a non-encrypted volume, will the copied files be encrypted on the destination?
