rfs is a shell script for creating and updating a local spare system disk. rfs's 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 "sauver_sys.sh", a shell script written by Eric Gerbier http://eric.gerbier.free.fr . rfs stands for "replication of file systems".
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.
Requirements:
· a backup disk : same size or bigger than the disk to clone
· sed-3.95 or later
· rsync 2.5.6 or later
· lilo 5 or later
Usage:
To clone /dev/hda on /dev/hdb , become root and type :
rfs /dev/hda /dev/hdb
If your system disk crashes, put the target disk in place of the source one, and reboot.
