luks-cryptsetup-backup

If you encrypted your disk/partition, the lock is stored in the luks header. But if that one is broken, you cant decrypt anything even if you remember your key and all data is lost.

i think its not about the camera, but about the screen you are seeing the recording on. Imagine taking a video in landscape but having to check what you are recording in portrait. What would i want that disadvantage for?

Btw i find the many people who watch wide screen videos in portrait mode fucked up.
