Submission + - How to encrypt and backup your hard drive
linjaaho writes: It is easy to back up your files with Dropbox, Mozy or similar service, and it is easy to encrypt your hard disk or some subset of files with Truecrypt or similar. But how to do backup to a remote server *and* store them encrypted on your local hard disk? For tens of megabytes it is easy: just make an encrypted volume with Truecrypt and every evening copy it to a remote server, or use Dropbox to store it.
But how to back up a large set (gigabytes or more) of files, or maybe your whole home directory *and* keep it encrypted on your laptop? It is not possible to copy an encrypted image of to a remote server every day, if it contains for example 50 gigabytes of data.
Such a solution would make it possible to sleep well after — and before — someone steals your laptop.
