What sort of setup would you have for secure file storage on a VPS? (lemmy.blahaj.zone)

Purely a hypothetical for me; I don't have the means for a VPS or that many files. But in the future, if I'd want to use the 3-2-1 rule with a VPS subscription, what sort of software would I need to ensure that my files can't be accessed on the VPS and need off-site decryption keys? What kind of setup would allow you to access said files from a different device if the decryption keys are stored locally on it? People who've done something similar, how has that gone for you?

Not only does borg have strong encryption, it also has git-like incrimental versioning and insanely good compression and de-duplication.

For example, I backup my whole 700GB OS drive (personal data + the whole linux OS install with all my tweaks and configs) - I set it to keep the last 15 "snapshots" (7 daily, 4 weekly, 3 monthly, 1 yearly) and all it takes on the borg server is 800GB.

I like using borgmatic for automatic borg backups, but it's optional.
