More Information
Summary:A journaling file system may implement remote durable logging. Updates to a file system may be received, and log records describing the updates may be stored in a locally-accessible file system change log. The update may then be acknowledged as committed. The log records may then be sent to be stored in a network-based data store in a remote version of the file system change log. Once it may be determined that the log records are stored in the remote version, storage space for the log records in the local file system change log may be reclaimed. Various types of restoration and duplication techniques may be implemented based on the remote version of the change log to restore a file system at an originating device or to duplicate the file system at a different device.
