If you like me use PGP Whole Disk Encryption to protect your Mac you might have discovered that your Time Capsule backups are stored completely un-encrypted. This means if someone steals your Time Capsule disk they will get full access to all your emails and files, even if you have encrypted your system disk. Based on some old tips I have found on the web I have put together a complete guide on how to encrypt and decrypt Time Capsule backups so you can use them both for backup as well as restore.
