etckeeper-ng

Etckeeper-ng is a bash script which uses git and rsync awk sed and find to create a backup directory of your /etc linux directory.
It is easy to configure. The default configuration should work on most boxes. Just make sure you have git rsync and all the other requirements installed.
When you use the etckeeper-ng the first time open a terminal and type "etckeeper-ng init" to create your first initial backup or "etckeeper-ng help" to show the help for this script.
