There are good options. Borg, rsync.net with zfs send/recv. Storage boxes from Hetzner
Hard to make a particular recommendation as backing up to the cloud is a popular option but depends on your upload speed and rate of data change. And depends how much you're willing to spend for what tradeoff
Storage box from hetzner is great. Hetzner is a good company, I'm glad that I'm doing business with them. The service is good, cheap, reliable, and... Un-american which means it would probably stay good and won't enshitify.
Use Hetzner! I'm not affiliated just a happy customer.
i use hetzner too, and I like their current services. But I think we all do good in never assuming or relying on ANY company being our friends. Be vigilant
