After the starting of operation on December 1998, Subaru Telescope ARchive System(STARS) continued to store and manage the data taken at the summit of Mauna Kea, Hawaii, and total amount of data is currently about 3 TB in amount or ~ 600,000 files. The data production rate is increasing gradually with increasing stability of telescope and instrument operation. There were some upgrades in STARS itself after our report performed in the last SPIE meeting held in Munich on March 2000, and also were some new features developed and established in Mitaka, Japan for mirroring all data stored in STARS. We also started the releasing the data whicv passed the proprietary terms to world wide via seperate system. We will discuss about the concepts and current status of our distributed archive systems in detail, and its impact to scientific or enginieering return from Subaru telescope.
