I've setup two VM Guests on Hyper V 2008 R2 Server. All good except I'm having to backup to 1 TB USB Drives. Basically the whole system backup selection is about 900GB. It's getting close to what the 1 TB drives can hold. I have found that it is expected behaviour for Hyper V to create the .bin file equal to the amount of RAM on the VM guests. In my case this equals around 50 GB. Can I exclude these .bin files from my backup?
There are no snap shots of these machines, the .bin are purely related to the running machine. If I shut the machines down the .bins dissapear. I'm just looking at NOT" backing up 50 GB of unrequired data.
