I have been using VirtualBox for a while now using it as my development server. I am a little paranoid, so I run a backup of the VM every night, and I also run a backup of code and data within VirtualBox that backs it up on an external drive.
Do you think the 2nd part is necessary though? I mean....backing up the virtual drive should be enough I would hope.
How are others backing up there data on the VM?
