S3 Spaces Sync plugin connects your Media Library to a container in DigitalOcean Spaces. It syncs data from your website to cloud storage and replaces links to images (optional). You may keep the media locally (on your server) and make backup copy to cloud storage, or just serve it all from DigitalOcean Spaces.
In order to use this plugin, you have to create a DigitalOcean Spaces API key.
You may now define constants in order to configure the plugin. If the constant is defined, it overwrites the value from settings page.
There is a known issue with the built in WordPress Image Editor, it will not upload changed images. Know how to fix this, PR welcome.
