I don't backup my computer anymore because everything I have is in the cloud anyways. I have a git repository with all of my scripts, a command I run to set up my system from scratch, and all of my files in Google Drive/Github. Any Steam games I play either automatically store my information online, or aren't important enough for me to worry about. The only think I would loose if my computer broke was my downloads folder, pretty much.
The only thing I customize in my browser is the color scheme, and my script updates that manually. I mean I have some bookmarks and extensions, but those don't take more than 10 minutes to restore.
