ABSTRACT:
A mirror file systems (MFS) is a virtual file system that links two or more file systems together and mirrors between them in real time. The file systems linked and mirrored through the mirror file system can be a local file system connected to a physical device, or a network file system exported by a remote system on a network. The mirroring mechanism is established by linking a file system to another file system on a single directory through an MFS mounting protocol. User applications perform normal file system operation and file/directory operation system calls like open, read, write and close functions from the pathname of either file system. When updates occur, such as a write operation, the MFS mechanism ensures that all data updates go to both the file systems in real time.
