We found the following APIs to be redundant or less useful outside of AWS S3. If you have a different view on any of the APIs we missed, please open a [github issue](https://github.com/minio/minio/issues).

###  List of Amazon S3 Bucket API's not supported on Minio.

- BucketACL (Use [bucket policies](http://docs.minio.io/docs/minio-client-complete-guide#policy) instead)
- BucketCORS (CORS enabled by default on all buckets for all HTTP verbs)
- BucketLifecycle (Not required for Minio erasure coded backend)
- BucketReplication (Use [`mc mirror`](http://docs.minio.io/docs/minio-client-complete-guide#mirror) instead)
- BucketVersions, BucketVersioning (Use [`s3git`](https://github.com/s3git/s3git))
- BucketWebsite (Use [`caddy`](https://github.com/mholt/caddy) or [`nginx`](https://www.nginx.com/resources/wiki/))
- BucketAnalytics, BucketMetrics, BucketLogging (Use [bucket notification](http://docs.minio.io/docs/minio-client-complete-guide#events) APIs)
- BucketRequestPayment
- BucketTagging

### List of Amazon S3 Object API's not supported on Minio.

- ObjectACL (Use [bucket policies](http://docs.minio.io/docs/minio-client-complete-guide#policy) instead)
- ObjectTorrent

### Object name restrictions on Minio.

Object names that contain characters `^*|\&#34; are unsupported on Windows and other file systems which do not support filenames with these characters.
