Ask HN: What do you use to digitize your paper records?

I'm looking at digitizing most of my personal paper records like tax files, large value receipts, important letters, legal documents etc. The plan is to scan them to PDF or TIFF using a feed scanner. I want a solution that encrypts and backs up to the cloud. Anyone doing this? Suggestions for a good system and tools for this requested. Thanks!

Edit: So far I've found Cryptomator (https://cryptomator.org/) which seems like a good open source secure vault on top of my existing Dropbox/Google Drive storage.
