Distributed File System (DFS) is a set of client and server services that allow an organization using Microsoft Windows servers to organize many distributed SMB file shares into a distributed file system. DFS has two components to its service: Location transparency (via the namespace component) and Redundancy (via the file replication component).
In computing, a distributed file system (DFS) or network file system is any file system that allows access from multiple hosts to files shared via a computer network.This makes it possible for multiple users on multiple machines to share files and storage resources.
Upload/download model: The client can access the file only locally. It means that the client has to download the file, make modifications, and upload it again, to be used by others' clients. The file system used by NFS is almost the same as the one used by Unix systems. Files are hierarchically organized into a naming graph in which directories ...
DFS Replication is a state-based replication engine for file replication among DFS shares, which supports replication scheduling and bandwidth throttling. It uses Remote Differential Compression to detect and replicate only the change to files, rather than replicating entire files, if changed. Windows Vista also includes a DFS Replication ...
A POSIX DFS focused on fault-tolerance and high-performance, based on the Mojette erasure code to reduce significantly the amount of redundancy (compared to plain replication). Scality: Scality ring Proprietary: Linux: A POSIX file system [citation needed] focused on high availability and performance. Also provides S3/REST/NFS interfaces. Tahoe ...
DCE/DFS is a DCE-based application which provides a distributed filesystem on DCE. DCE/DFS can support replicas of a fileset (the DCE/DFS equivalent of a filesystem) on multiple DFS servers - there is one read-write copy and zero or more read only copies. Replication is supported between the read-write and the read-only copies.
The replication itself should be transparent to an external user. In a failure scenario, a failover of replicas should be hidden as much as possible with respect to quality of service. [4] Computer scientists further describe replication as being either: Active replication, which is performed by processing the same request at every replica
Google File System (GFS or GoogleFS, not to be confused with the GFS Linux file system) is a proprietary distributed file system developed by Google to provide efficient, reliable access to data using large clusters of commodity hardware.
