How do I backup my system so that if I do backup today, tomorrow when I recover it it's totally the same as yesterday? I mostly care bout system itself, programs and documents are not that important but still would be nice to keep programs+settings for them. I need it in case I do something dumb: purge needed package, mess up linux-headers, repository, tweak registry and fail and so on.
- messed up with XConf and it's not working.
- used gconf-editor, did some changes and forgot where I did them, gconf-editor doesn't have undo or "don't save" feature, so I am wondering what the hell did I change?
and so on.
- and so on, one more thousand stupid mistakes of a guy who is noob at Ubuntu but likes it and wants to become pro :)
