I'd highly suggest Syncthing over this solution - no need to rely on 3rd parties for your data storage, let alone trust them with unencrypted copies of your data, if someone malicious worked at DigitalOcean and wanted to compromise you, it'd be trivial to put a malicious script in your Vault files. Especially if deplatforming is a concern something like Syncthing would avoid any reliance on a 3rd party that has visibility into your data.
