You can use MinIO as a replacement for Amazon S3 for both S3 Archiving and Bucket Storage.

Follow these guides, and remember to set S3_STORAGE_ENDPOINT_BASE=http://my-own-s3:8080 or S3_ARCHIVING_ENDPOINT_BASE=http://my-own-s3:8080 to make sure your installation goes to your local instance of MinIO rather than Amazon S3 by default.

For your Humio environment to work properly with MinIO, set BUCKET_STORAGE_IGNORE_ETAG_UPLOAD=true in your configuration, to disable checksum matching while uploading the file; however the file integrity is still ensured.
