I have an old Windows 2008R2 virtual machines with 2 virtual disks, one of 50GB another of 120GB (more or less). I have replaced this VM server with another VM so I want to "warehouse" this VM, store it, backup it up so I can get to in the event we discover something on the new VM we did not transfer from the old. What is the best way to do this? The MAIN GOAL is to minimize the size of the virtual disks? Drive C (the 50GB drive) only has about 20GB of space used and Drive D (the 120GB) is only using about 70GB. In other words is there a process that will allow me to only backup, export, ???? that only what is being used, so as to reduce the size of the virtual disks to something close to the actual space used? That way if I do have to get to it (restore it, import it) it will be 2 drives of 20GB and 70GB instead of 50 and 120? Again, the MAIN GOAL being that we want to minimize the size of the virtual disks? Thank you very much.
