I have all the programs installed, games and all. The whole system partition takes 55GB, 30 of which=games. An ATI image of this would be about 50GB. I venture to guess a snapshot of this would be around 55GB as well. What I want to do is simple, have 4 different snapshots: snapshot 1. Working copy- The full thing, just as it is, for the normal days. snapshot 2. Playing copy - Just the games and optimized services /hardware config for games. snapshot 3. More playing copy-testing softwares, probably the bare/updated OS. etc... snapshot 4. Rollback copy- This should just be duplicate of snapshot 1. duplicates of snapshots 2 and 3 will be on external disk. Now, how do I do this without having to uninstall and Reinstall my games and settings? I can start @snapshot 1. Then, optimize for games and uninstall everything else, then make snapshot 2? After that, restore snapshot 1, uninstall all games, leaving just the OS and make snapshot 3? After that, restore to snapshot 1 and copy to snapshot 4?
