FileVault is macOS's built-in encryption tool, protecting your data from being decrypted or having unauthorized access. The tool uses an AES-XTS data encryption algorithm to protect internal and external storage devices. Let's explore the complete process for securing your Time Machine Backups with FileVault full-volume encryption.

Step 4. The following dialog box displays the recovery keys you will need to unlock your disk drive if the hard disk is removed from the machine and needs to recover data or the user passwords don't work. 

Step 5. FileVault will start encrypting the entire volume. It may take some time, depending on the size of your volumes and the information stored on your Mac.
