I have a few VMs that I've created (which I want to use as a base machine for program testing). So, what I want to do is back up these machines since they are "fresh" installs and fully updated, because I want to be able to restore them if needed for if one gets corrupted during software testing.
Can I just copy the Virtual Machines folder to an external hard drive, or is there a tool I need to use to make a backup copy of my virtual machines to another hard drive for storage and recovery. I want to get them off my machines so also if my hard drive crashes on my workstation machine, I can simply restore them later.
