Thanks for your quick reply.
This is really the bizarre part.. This vm is running a similar 2012 R2 like other 3 vm (just one vm is running centOS). This is my first time using veeam on hyper-v. I simply installed the base veeam free and then found out about patch#4. Seeing #4 was inclusive of all previous patches I didn't install patches 1,2,3 separately. Wondering if that has anything to do with these 0.0kb sizes on this just one vm.
Should it matter which guest Applications are running in this guest OS? For example this vm is running Plesk? Plesk is know to hog and control resources..
