Back up from TrueNAS to MinIO S3 Target

As part of my backup strategy, I would like to back up to a MinIO instance on a separate TrueNAS Scale system (I currently have snapshots replicating to a third system offsite). However, I am having trouble configuring the cloud credentials. Has anyone had any success setting this up?

Both systems are running TrueNAS Scale 24.04.0 and I have MinIO installed through the main app repository. I have set up a bucket and created a user with access privileges to that bucket. When setting up the cloud credentials, I am entering the Access Key ID and Secret Access Key of the new user and enter the secondary TrueNAS IP address of the Endpoint URL. I have even tried the root user login info entered when the app was first created. None of this has worked for me. Appreciate any help on this.

Thank you!

Hi, did you find a solution?

I have tried to backup to MinIO that is hosted on another TrueNas Scale Server and was able to perform it with no error. Maybe it has something to do with your Enpoint URL? Make sure the port number is included.

MinIO S3 is compatible with Amazon S3.
