RFS is a shell command that helps you build and maintain a spare system disk on your local machine. It simplifies the process of creating and updating a system backup with shell scripts.
Originally known as "sauver_sys.sh," rfs was originally authored by Eric Gerbier. The name itself is an acronym for "replication of file systems," and the software is designed to work on Gnu/Linux platforms and support both ext2 and ext3 file systems.
Whether you're using a workstation or a server, rfs is the ideal choice for maintaining a fully-working backup system while the primary system is being cloned or otherwise maintained. All you need to get started is a backup disk that's the same size or larger than the disk you plan to clone, along with some basic tools like sed-3.95 or later, rsync 2.5.6 or later, and lilo 5 or later.
Once all your tools are in place, using rfs is simple: just become root and type "rfs /dev/hda /dev/hdb" to quickly clone /dev/hda on to /dev/hdb. If disaster strikes and your system disk crashes, all you need to do is replace it with the target disk and reboot.
Overall, rfs is a reliable and versatile tool that's perfect for anyone looking for a convenient and efficient way to maintain a fully-working backup system at all times. Whether you're a seasoned system administrator or a casual user, this powerful tool is sure to come in handy time and time again.
