业界普遍认为解决企业文档安全存储问题应包括集中存储、权限控制以及流程管控3个方面。集中存储是基础，在实现数据统一管理的同时，也带来了新的安全风险和需求，如容量扩充、灾难恢复、访问受控等。采用私有云存储解决企业文档的安全存储已为业界普遍看好，但是目前建立私有云存储方案的高昂成本以及由此而导致现有IT设施的浪费却难以为众多企业所承受。文中描述了广州国迈科技的魅云分布式文件系统的设计原理，它结合了目前商用云存储系统的核心技术思想，强化了面向企业文件操作和管理的安全性特征，在企业现有的IT设施基础上实现了文件存储的海量支持、弹性扩容、冗余备份、故障恢复、异地备份、透明使用、安全可靠等重要功能。

The point of view widely accepted by the industry is that the solution of problems in safe documents storage lies in the three aspects including centralized storage, access control and process control. As the foundation of solution, centralized data management would bring new risks and also new safety requirements, such as dynamical capacity expansion, disaster recovery and controlled access. The private cloud computing is generally regarded as a better way, but the high cost in its infrastructure construction is hardly accepted by most local companies. This paper describes the design principle of Charming-Cloud distributed file system developed by Guangzhou Goldmessage Technology Co. Ltd.. This system, based on the core technology of commercial cloud storage system, enhances the safety features of file operation and management and realizes the important capabilities such as mass storage, dynamical expansion, redundancy backup, fault recovery, remote backup, transparent use, safety and reliability etc.
