Of course. My setup now is a Proxmox server + a NAS. What I’m planning to do is to install a service for this to Proxmox, then have the files synced over NFS to the NAS, which then backs them up every night to Backblaze. And of course I need to have the paper copies too, but to be able to search, tag and archive the documents is great when you need to remember a thing X that was mentioned in a paper I got back in 2014.
