rfs

Purpose of rfs

rfs stands for "replication of file systems".

It is a shell script for creating and updating a local spare system disk. The main goal is to recover a working system after a crash quickly. In this case, "quickly" means the time it takes to reboot the machine. The very first version of rfs was clonedd.sh, a shell script written by Eric Gerbier.

rfs works on Gnu/Linux platforms and supports ext2/ext3 file systems. Targets are workstations as well as servers : your system remains fully-working while the backup is processed.

Terms of use

rfs is free and licensed under the General Public License : you can use it, modify it at your convenience. If you plan to embed it in a (commercial) package, remember this package has to conform with the General Public License. See file COPYING for details.
