I'm about to encrypt my hard drive with PGP Whole Disk, since Filevault just isn't good enough. I want encrypted backups too, and don't want to use standard OS X encrypted disk images. I plan to backup to a Truecrypt image or Truecrypt encrypted disk with either Time Machine or Super Duper. Has anybody done this? To restore from a backup, I'd assume I'd first need to decrypt the backup disk, then restore it from the OS X installer as usual. Would this work? Has anybody done this before? So long as I copy all files, visible and invisible, everything should work fine - right?
