Everything important, which was not already send by e-mail, is e-mailed to myself. I use gmail. When something is still on paper, I make a photo. If it is just a file I got from another medium, I just attach it. For note taking I prefer apple notes, but every once in a while, I just email the important notes. Why e-mail? Because it is an open standard, it will be readable in the far far future. I can easily migrate to another provider, or make backups with imap functionality. I backup my gmail with another gmail account which I check yearly to keep it alive. Email is also something which I always have at hand: on my phone, but I can also email to myself on another computer or from another account. Mail search in gmail is also quite alright.
