Is there such a thing as a restore point in Ubuntu?
I'm new to linux (Ubuntu 12.04) and I'm finding that as I try to do new things, I end up breaking parts of my installation. It would be very useful if there is an easy way to back things up so that I can revert to a previous working version of my environment. What's the best (and simple) way to do this?
I'm thinking it must be something like a Windows Restore point, but some of my searches have found people specifically saying there's nothing like that (it is not how linux 'works').
