20+ years ago, Lindows had a great app store that let you create an “aisle” of your favorite apps so if/when you’d reinstall your OS, instead of searching and installing all your apps one-by-one, you’d just go to your aisle, click “install all” and boom.
Is there anything that exists like that today?
One other thing I didn’t mention is it depends on the backup tool you use. Not all of them are filesystem aware. What that means is if you have hardlinks present those will not be preserved.
That can be important to remember as it will bork things down the road with the restoring. If you aren’t familiar with linking: Hard links point to actual data (think of it like a pointer in C). Soft links (symbolic) point to file path.
