One of the nice additions to VBR v8 is the ability to back up a single VM within a job using Quick Backup. I especially like the fact that they extended this ability to the vSphere Web Client, making it as simple as a right click. You can read more about this functionality on Veeam’s blog:

After reading this post and using the feature a few times, I figured there would be no need to update the Single VM Backup script. It turns out there is still use for a script such as this which was pointed out to me in the comments (Thanks Phil!). Essentially the Quick Backup feature only works on VMs that have previously been backed up, it does not work for new VMs.
