OpenRFS aims to be a replacement for replicated file system. With OpenRFS you may have sincronized filesystems between two machines in real time.

OpenRFS not implement any filesystem at low level, it simply envolve a directory with FUSE and log all operations in a database for send to another machine. It uses librsync to send changes, that makes no need for send entire large files when changes are small.

Linux: Make sure you have basic development tools and the kernel includes the FUSE kernel module. Then unpack the source tarball and type:

./configure
make
make install # or 'sudo make install' if you aren't root.
