New Concept in File Saving
The basic idea is simple. Every time a file is written, the changes are also saved immediately across the network to another system in a remote location. At any given time, there are always two live, active copies of the file in two separate locations.
Advantages
- With the NFS and CIFS protocol as the transport layer, there is no need to re-invent the wheel with a proprietary protocol.
- Only one copy of software is needed, on the active system. The NFS infrastructure on the remote system takes care of all replication operations from the active system.
- The two systems can be at geographically-dispersed locations, separated by hundreds of miles.
- The MFS works with any remote system and NAS that supports NFS and CIFS.
- The MFS works with any type of local and remote storage devices.
- NFS and CIFS check the syntax and semantics of every replication operation (create, write, delete) to maintain the integrity of the file system.
- Files on the remote system are ready to be used immediately.
- The file systems on both systems are active. When failover occurs, there is no need for file system check and mount operations.
