S3 Client

Coolify uses MinIO’s client, called mc, to copy the backup files to your S3 compatible storage.


To be able to use your S3 compatible storage, you need to verify it first. Verification done with ListObjectsV2 request to your specified bucket.

So you need to create a bucket first, and then you can verify it.
