Need of storing a huge amount of data has grown over the past years. Whether data are of multimedia types (e.g. images, audio, or video) or are produced by scientific computation, they should be stored for future reuse. Users also need their data quickly. [2,5]Data files can be stored on a local file system or on a distributed file system. Local file system provides the data quickly but does not have enough capacity for storing a huge amount of the data. On the other side, a distributed file system provides many advantages such as [7]scalability, security, capacity, etc. In the report, we will provide the state of the art in DFS oriented on reliability and performance in thesetype of systems. First of all, traditional DFS like AFS, NFS and SMB will be explored. These DFS were chosen because of their regular usage. Next, new trends in these systems with a focus on reliability and increasing performance will be discussed. This includes the organization of data and metadata storage, usage of caching, and design of replication algorithms and algorithms for achieving more reliability.
