In order to solve the problems such as poor data storage efficiency, data security and reliability, low resource utilization and high input costs existing in current cloud storage, an Hadoop-based efficient economic cloud storage system is proposed. The techniques of Hadoop, an efficient resource scheduling method and a probabilistic redundant scheduling are presented for the system to efficiently organize "free" computer storage resources existing within enterprises to provide low-cost high-quality storage services. The proposed methods and system provide valuable reference for the implementation of cloud storage system.
