Abstract： After years of observation, Xinjiang Astronomical Observatory(XAO) Nanshan 26 meters radio telescope (referred to as NSRT) had accumulated massive scientific data. A remote backup system was established for the online data storage of NSRT, this redundant storage system contains two storage clusters, one cluster was in XAO headquarters and another one located in Nanshan station, the real-time synchronization of NSRT data can be realized between two storage clusters. Based on the object storage technology, centralized Luster storage system was created for storage clusters, and the I/O performance test of luster systems was finished. Redundant storage system solved the online archive and data safety issue for NSRT data.
