Well, a VM is just a couple of data files. You should be able to back it up with some standard backup tools.

I’m not involved with the OS but was asked to recommend a utility or product to back up the linux system. The OS group is primarily a Windows based team. Any suggestions on a more user friendly alrternative than dd would be appreciated.

If the VM snapshot technology is really good, these might be very efficient on storage and other resources. Failing that, you should think probably about backing up the Linux filesystems exactly the same way you would a physical server.
