 By default {{es}} communicates with your storage system using HTTPS, and validates the repository’s certificate chain using the JVM-wide truststore. Ensure that the JVM-wide truststore includes an entry for your repository. If you wish to use unsecured HTTP communication instead of HTTPS, set `s3.client.CLIENT_NAME.protocol` to `http`.

Other S3-compatible storage systems may also work with {{es}}, but these are not covered by the {{es}} test suite.

 There are many systems, including some from very well-known storage vendors, which claim to offer an S3-compatible API despite failing to emulate S3’s behavior in full. If you are using such a system for your snapshots, consider using a [shared filesystem repository](shared-file-system-repository.md) based on a standardized protocol such as NFS to access your storage system instead. The `s3` repository type requires full compatibility with S3. In particular it must support the same set of API endpoints, with the same parameters, return the same errors in case of failures, and offer consistency and performance at least as good as S3 even when accessed concurrently by multiple nodes. You will need to work with the supplier of your storage system to address any incompatibilities you encounter. Don't report {{es}} issues involving storage systems which claim to be S3-compatible unless you can demonstrate that the same issue exists when using a genuine AWS S3 repository.
 
 You can perform some basic checks of the suitability of your storage system using the [repository analysis API](https://www.elastic.co/docs/api/doc/elasticsearch/operation/operation-snapshot-repository-analyze). If this API does not complete successfully, or indicates poor performance, then your storage system is not fully compatible with AWS S3 and therefore unsuitable for use as a snapshot repository. However, these checks do not guarantee full compatibility.

+[MinIO](https://minio.io) is an example of a storage system that provides an S3-compatible API. The `s3` repository type allows {{es}} to work with MinIO-backed repositories as well as repositories stored on AWS S3. The {{es}} test suite includes some checks which aim to detect deviations in behavior between MinIO and AWS S3. Elastic will report directly to the MinIO project any deviations in behavior found by these these checks. If you are running a version of MinIO whose behavior deviates from that of AWS S3 then you must upgrade your MinIO installation. If in doubt, please contact the MinIO support team for further information.

+The performance, reliability, and durability of a MinIO-backed repository depend on the properties of the underlying infrastructure and on the details of your MinIO configuration. You must design your storage infrastructure and configure MinIO in a way that ensures your MinIO-backed repository has performance, reliability, and durability characteristics which match AWS S3 in order for it to be fully S3-compatible. If you need assistance with your MinIO configuration, please contact the MinIO support team.

 Most storage systems can be configured to log the details of their interaction with {{es}}. If you are investigating a suspected incompatibility with AWS S3, it is usually simplest to collect these logs and provide them to the supplier of your storage system for further analysis. If the incompatibility is not clear from the logs emitted by the storage system, configure {{es}} to log every request it makes to the S3 API by [setting the logging level](/deploy-manage/monitor/logging-configuration/update-elasticsearch-logging-levels.md) of the `com.amazonaws.request` logger to `DEBUG`.
 
 To prevent leaking sensitive information such as credentials and keys in logs, {{es}} rejects configuring this logger at high verbosity unless [insecure network trace logging](elasticsearch://reference/elasticsearch/configuration-reference/networking-settings.md#http-rest-request-tracer) is enabled. To do so, you must explicitly enable it on each node by setting the system property `es.insecure_network_trace_enabled` to `true`.
