Patent abstract
Data is durably backed up for a limited amount of time. The data may be encrypted under a key and the key may be encrypted under a backup key. The backup key has a limited lifetime at the end of which the backup key is destroyed. After the backup key is destroyed, recoverability of the data depends on whether the key was deleted. In some examples, the data is a set of cryptographic keys.
