Abstract
The disclosed embodiments provide a system that processes data. The system includes a first client that encrypts a first set of data, uploads the encrypted first set of data to a volume on a cloud storage system, and creates a commit record of the upload. The system also includes a synchronization server that verifies access to the volume by the first client and includes the commit record in a change set containing a set of commit records associated with the volume. The synchronization server also signs the change set and provides the change set for use in synchronizing the upload with a second client.
