### Cluster-readable probe

The reply is '200 OK' if cluster has read quorum if not it returns '503 Service Unavailable'.

- Creation of STS credentials
- Creation and deletion of service accounts (except those owned by the root user)
- Changes to Bucket features such as:
  - Bucket Policies
  - Bucket Tags
  - Bucket Object-Lock configurations (including retention and legal hold configuration)
  - Bucket Encryption configuration

> NOTE: Bucket versioning is automatically enabled for all new and existing buckets on all replicated sites.

The MinIO server requires an available KMS to en/decrypt SSE-S3 encrypted objects. Therefore it is possible to erase or lock some or all encrypted objects. For example in case of a detected attack or other emergency situations the following actions can be taken:

	if ! checkBucketExists $BUCKET; then
		if [ ! -z $OBJECTLOCKING ]; then
			if [ $OBJECTLOCKING = true ]; then
				echo "Creating bucket with OBJECTLOCKING '$BUCKET'"
				${MC} mb --with-lock myminio/$BUCKET
			elif [ $OBJECTLOCKING = false ]; then
				echo "Creating bucket '$BUCKET'"
				${MC} mb myminio/$BUCKET
			fi
		elif [ -z $OBJECTLOCKING ]; then
			echo "Creating bucket '$BUCKET'"

### Create a bucket for Veeam backups

Create a bucket for Veeam Backup, e.g.,

```
mc mb myminio/veeambackup
```

> NOTE: For Veeam Backup with Immutability, create the bucket with object lock enabled, e.g.,

```
mc mb -l myminio/veeambackup
```
