Abstract

Techniques for secure data synchronization are described. In one or more implementations, techniques may be employed to conserve high cost data storage by storing larger portions of encrypted data in low cost storage, while storing relatively smaller encryption keys in higher cost storage. A device that is granted access to the encryption keys can retrieve the encrypted data from the low cost storage and use the encryption keys to decrypt the encrypted data.
