I would love to be able to configure time machine to only back up a list of directories. I keep my files organized in specific directories in my homedir, “dev”, and “personal”. I would like those to be backed up and nothing else. My guess is that something like this would be much less prone to bugs and much quicker to run. I realize some people have a perfect and/or high complex setup that they want to be able to come back to if their system fails, but my experience over the last 10 years has taught me that restoring from a time machine back up is extremely rare. I would rather just make sure my important files are backed up (at the click of a button, or automatically) and I can easily rebuild my system by reinstalling things from scratch.
