CryptoStacker, long term vision

A related topic to encrypted disk drives. Anybody who has a desire to see their data around long term makes backups of their drives. At least one of these backups is usually physically near the drive in question. What good it is to have an encrypted disk if the backups are not also encrypted? Backups occur at the file system level, where an encrypted file system does not appear encrypted, so that work here does not directly leverage to encrypted backups. Eric
