To fulfill my backup needs, I use two simple bash scripts.

• rsnapshot.sh which periodically takes snapshots of a specified folder using rsync and hardlinks. You could then browse the past states of your folder with your filebrowser.

• teletime.sh which allows you to run programs so they see the past versions of files instead of current ones.

These scripts are very helpful when I do computational experiments with ipython notebook. Without the risk of losing something, I could modify my files as I can always go back in time with this setup.
