摘要： A client-side deduplication library receives from a backup application at a client a job request for a file-copy operation involving one or more files managed by a backup server. A server-initiated communication channel is established between the backup server and client-side deduplication library. A callback from the backup application specifying one or more types of status updates that the application wishes to receive is registered. The backup server is directed to start a job for the file-copy operation. A status update on the job is received over the server-initiated communication channel without having to prompt the backup server for the status update. If the status update is of the type that the backup application wishes to receive, the callback is called to notify the backup application of the status update. If not, the callback is not called.

摘要： A load balancing algorithm and cluster configuration details are stored at each of a set of namespace nodes of a cluster hosting a deduplicated file system. Upon a client connecting to a namespace node, a server-initiated communication channel is established between the namespace node and the client over which updates to the load balancing algorithm, cluster configuration details, or both are sent. The load balancing algorithm and cluster configuration details are sent to the client, thereby allowing the client to determine according to the load balancing algorithm and cluster configuration details, which particular namespace node should handle a particular file system operation. Thereafter, each connected client is immediately notified of changes to the cluster such as node or service additions or deletions or software upgrades to the cluster so that each client can use the updated information to conduct load balancing.
