My solution is surprisingly Microsoft OneDrive, but hear me out. I have the family plan that gives you 1TB per account and you can have up to 6 in the family, giving you a total of 6TB. The thing is, I don't trust Microsoft, so I use rclone with a crypt remote that encrypts everything before it reaches OneDrive and the encryption key lives in the rclone config on my machine. Make multiple local copies of this file and you're all set. You can replicate this with any storage provider and you don't have to trust them.
