"Better backup" aside, as I understand that I'd miss out on deduplication and all the other things backup software can do like keeping track of what it has backed up etc. "Better encryption": Can you explain why age's encryption isn't sufficient if it's recommended for encrypting files? Really want to understand how it's recommended for encrypting and sharing a file over an untrusted channel like email, but not recommended to encrypt a file and upload it to an untrusted server.
