I downloaded Lion OS X (an upgrade on top of Snow Leopard) but my MacBook pro is becoming quite slow now. I'd like to install a fresh new copy of Lion OS X. I know how to do that, I can just re-download Lion from the App Store and there are a ton of tutorials online on who to do a fresh install.
My question is, how would I back up my documents? Logically, I would like to keep almost all my files and apps. I do have Time Machine. Can someone suggest to me how I should back up and then restore my apps and files and all that? That also includes apps I purchased not through the App Store, like Office and Mailplane. I'd like to continue to use those..
If someone knows of a way to optimize my machine without going through all this, could you please suggest to me what to do? It's becoming really slow and I hate it.
