> I believe even encrypted backups can be cracked. If anything, they're more prone to being cracked, since an attacker can load the backup onto a very fast system and run custom software which can run many permutations of keys against the backup to try to unlock it. With actual hardware, they're limited by having to manually enter the key in most cases plus any hardware or OS features which would notice that the user has entered too many incorrect passwords and lock down the device further. On the other hand, if the computer that your backup has been backed up to is itself reasonably locked down, that might be an acceptable trade-off; they can't try to crack a backup they can't access in the first place.
