What are some of the best back up practices?
For example, I recently messed up Ubuntu by doing something stupid. I had to reinstall Ubuntu. It did not take long, but I would like to have a backup of some sort that I could easily restore. Things like Norton Ghost for Windows are nice since you can ghost a working installation and then be back up and running in a few minutes in this situation.
I have read about Clonezilla, but never used it.
Also, is there some type of system restore in Ubuntu?
