Constructing Private Cloud Storage Using Network Attatched Storage

Human has entered the "cloud age" today, many resources can be put into cloud for further using and exploit. However, putting confidential data or private data to the public cloud has the security issue. Moreover, the construction cost of typical cloud storage is too high and need a lot of management effort of hardware, which is not affordable by person, SOHO and small companies. They need low cost but robust solution to build their private cloud. Thus, in this paper, a low cost, flexible, and recoverable private cloud storage system using NAS is proposed. Two core techniques named "migration" and "cell recovery" for enhancing the flexibility and recoverability are introduced and evaluated. The results show that the system is practicable.
