چکیده

An on-line backup function for X-NAS, a clustered NAS system designed for entry-level NAS, has been developed. The on-line backup function can replicate file objects on XNAS to a remote NAS in real-time. It makes use of the virtualized global file system of X-NAS, and sends NFS write operations to both X-NAS and the remote backup NAS at the same time. The performance of the on-line backup function was evaluated and the evaluation results show that the on-line backup function of X-NAS improves the system reliability while maintaining 80% of the throughput of the X-NAS without this function.

It virtualizes multiple NAS systems into a single-file-system view for different kinds of clients. The core of X-NAS is a multi-protocol virtualized file system (MVFS), and its key features—a smart-code wrapper daemon, file-group mapping, and a file-handle cac...
