Abstract: A method is provided for performing distributed backup and retrieval of data. Data is sent by a plurality of client devices to be processed by a server and then stored in a database. A subset of the processed data stored in the database is backed up to each of the plurality of client devices. For the one or more particular client devices owned by a user, the subset of processed data stored on the one or more particular client devices is the subset of processed data that is associated with the user. The server and client device is updated to maintain the same state of processed data in the database and the backup. In the event of failure of either the database or a client device, processed data may be restored using the processed data stored on the database or the backup stored on the plurality of client devices.
