@thibaud Are you able to generate credentials for me to test your minio instance? Maybe just create a test bucket for us. Just send them to support@cloudron.io.
I just tried to setup backups to a minio installed on Cloudron and that works fine.
@seeker Ah, I see. I think you can actually use minio for this because it looks like you just want file storage? All the standard S3 modules will work with minio and it's very easy to integrate.
