I was looking for a good-enough backup solution for Ubuntu. After a few minutes of googling I settled for Back In Time http://backintime.le-web.org/ .
It wonderful, I can set it to backup my software every hour (or more, or less). Which keeps med happy. Sometime I do stupid thing like edit a document and press Ctrl-A and then enter, and then Ctrl-S and I dont realize this until the next time I open the document again.
It keeps snapshots of the filesystem. So that I can go back to every hour since it started. Never again loose a document!
It a one-click-install on ubuntu. And then create a folder, for example, Backups in your home directory. Then in Back in Time select which folder to backup and how often, and where the backups should go.
