The design and implementation of an extensible network backup system in realtime
Satoshi Nishimura, Mutsuo Sano, Ikeda Katsuo · 2009
This paper proposes a backup system based on mirroring filesystem "GMFS." GMFS has been developed to mirror data in realtime on the filesystem layer. The GMFS is a stackable filesystem which flexibly mirrors without changing the existing environment by operating as a wrapper of other filesystems.
