I like to copy all my game saves into my Dropbox folder, and then symlink them to their original location. This gives me two advantages, (1) my game saves are backed up in the cloud and (2) I can roll back my games saves to any change in the last 30 days. This means if the game corrupts my save, I can roll back to an earlier version. This isn't difficult to setup. Looking around Dropboxifier seems to wizard-ize the symlink setup (though using LSE as simply as making an application shortcut.)
1. Install Dropbox. Make an account.
2. Install LSE
3. Locate the folder with your save file. (Googling is usually quickest, "GameX save file location")
4. Move that folder to your Dropbox folder (C:\Users\YourUserName\Dropbox\)
5. Drag the game save folder (which is now in the Dropbox folder) back to it's original location using the right mouse button. On right button release select "Drop here"->"Symbolic Link" from the context menu.
Later when you want to roll back to a previous version, right click on the save file and select "Dropbox"->"View previous versions". That will open a webpage on the dropbox site that allows you to select which version you want to roll back to (e.g. 1 min ago, 3 min ago, 14 min ago, 22 hours ago, etc). Select the version you want and hit the restore button on the web page. Wait 5 seconds for your local file to update, then open you save in the game.
