What's the Net Effect of a Power Loss?

The net effect is basically like your power loss, or whatever kind of crash you had, didn't happen when it really happened. If you've got a disc only snapshot, it's crash consistent. You take the v m snapshot in the midst of it at a base transaction, it will obviously roll back that transaction. Now we're back to our power lost senario. It's just like you pulled the plug in the middle of something happening. However, it can still be important to understand the ference for back up and restoration reasons.
