A distributed file system over unreliable network storages

Nowadays, an individual uses multiple ICT devices such as PCs, laptops, smart phones and others. And the content files are not dedicated to a specific device, but shared by the devices. One of the sharing services is the personal cloud computing. Users can backup, synchronize, share and manage their files with it. But most cloud systems have their own dedicated interfaces and it is not easy to use files in various applications. We propose a distributed file system which works with the legacy internet protocols. Applications on devices can share files with the general file i/o interface, and our system enhanced reliability of file storages in both aspects of failures of servers and security risks.
