If you use VirtualBox, you might want to Backup your Disk Images. Since its a VM you would think this works simply by copying, but no, VirtualBox (or xVM as Sun calls it) needs to strip all the info binding the Image to a specific Machine first. Thats accually not a big Problem since VBox offers a tool for that (vboxmanage), but this tool has no Interface. Not willing to go to the Command Line everytime and remember the Command, I created a little script with a GUI frontend to do that for me, since I’m using a Mac I Packaged it (using py2app) so it seems more native.
If anyone needs it you can download it Here
Simply select VDI Folder, and the Folder to Backup to, and klick Backup.
