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

- BucketACL (Use [bucket policies](https://min.io/docs/minio/linux/administration/identity-access-management/policy-based-access-control.html) instead)
- BucketCORS (CORS enabled by default on all buckets for all HTTP verbs, you can optionally restrict the CORS domains)

// array position can be safely represented inside a JSON string, embedded
// inside of HTML <script> tags, without any additional escaping.
//
// All values are true except for the ASCII control characters (0-31), the
// double quote ("), the backslash character ("\"), HTML opening and closing
// tags ("<" and ">"), and the ampersand ("&").

# Access Management Plugin Guide [![Slack](https://slack.minio.io/slack?type=svg)](https://slack.minio.io)

MinIO now includes support for using an Access Management Plugin. This is to allow object storage access control to be managed externally via a webhook.

# Using MinIO with Veeam

When using Veeam Backup and Replication, you can use S3 compatible object storage such as MinIO as a capacity tier for backups.  This disaggregates storage for the Veeam infrastructure and allows you to retain control of your data. With the ease of use of setup and administration of MinIO, it allows a Veeam backup admin to easily deploy their own object store for capacity tiering.

## Prerequisites

	AcceptRanges       = "Accept-Ranges"
	AmzBucketRegion    = "X-Amz-Bucket-Region"
	ServerInfo         = "Server"
	RetryAfter         = "Retry-After"
	Location           = "Location"
	CacheControl       = "Cache-Control"
	ContentDisposition = "Content-Disposition"
	Authorization      = "Authorization"
	Action             = "Action"
	Range              = "Range"
)

// Non standard S3 HTTP response constants
const (

)

// startWithConds - map which indicates if a given condition supports starts-with policy operator
var startsWithConds = map[string]bool{
	"$acl":                     true,
	"$bucket":                  false,
	"$cache-control":           true,
	"$content-type":            true,
	"$content-disposition":     true,
	"$content-encoding":        true,
	"$expires":                 true,
	"$key":                     true,

in one bucket. For example, you could store `spark.csv` (version `ede336f2`) and `spark.csv` (version `fae684da`) in a single bucket. Versioning protects you from unintended overwrites, deletions, protect objects with retention policies.

To control data retention and storage usage, use object versioning with [object lifecycle management](https://github.com/minio/minio/blob/master/docs/bucket/lifecycle/README.md).  If you have an object expiration lifecycle policy in your non-versioned bucket...
