How much 'be able to access my files' do you need - constant refreshing, or just the ability to recover? Glacier will give you the latter, for a price, but is designed to be something that you only read from during an emergency. Writes / updates, and storage, are very cheap. Disclaimer - I work for Riverbed, who used to have a lovely product called WhiteWater, subsequently renamed SteelStore and sold to NetApp. This is a backup / archive system that uses whatever 'cloud' (not a word I'm fond of) backend you prefer. Data is de-duplicated at ingress, and encrypted at rest. It would require a local VM, but that's a small matter these days. No idea on pricing. If you're at all inclined, and primarily to address the '50+ years' requirement, you could look at rolling your own solution. Architecture would be (initially) something like a RPi with a 3TB drive - bought and installed at (at least) two friend's places. Perhaps a contra-deal arrangement with them. VPN for security & convenience. LUKS for at-rest encryption. Something sitting on top of rsync (over SSH) for in-transit encryption + file-level deduplication -- I use dirvish[1] for archives that are too large / too binary blobby for git. I've got two family members already doing rsync (using unison[2]) backups over the net to VMs I host that then get dirvished.
