I have a system which runs an arcade machine. It has the regular swap and root partitions, but then I have an extra partition which I call data. Data holds many gigabytes of game content.
The idea is that if anything goes wrong with the Linux system, I should be able to restore it from a backup and leave
My question is, what utility is best to backup and restore just the Linux system partitions? Can I just use
dd to make an image of
/dev/sda2, for example? What about the MBR - Master Boot Record?
