- All versions, including delete-markers should be deleted before deleting a bucket.
- **Versioning feature is only available in erasure coded and distributed erasure coded setups**.

## How to configure versioning on a bucket

Each bucket created has a versioning configuration associated with it. By default bucket is unversioned as shown below

```

	lastBlockSize := totalLength % fi.Erasure.BlockSize
	lastShardSize := ceilFrac(lastBlockSize, int64(fi.Erasure.DataBlocks))
	return numShards*fi.shardSize() + lastShardSize
}

// ShallowCopy - copies minimal information for READ MRF checks.
func (fi FileInfo) ShallowCopy() (n FileInfo) {
	n.Volume = fi.Volume
	n.Name = fi.Name
	n.VersionID = fi.VersionID
	n.Deleted = fi.Deleted
	n.Erasure = fi.Erasure

func (*parser) parseString(b []byte) string {
	if i := bytes.IndexByte(b, 0); i >= 0 {
		return string(b[:i])
	}
	return string(b)
}

// formatString copies s into b, NUL-terminating if possible.
func (f *formatter) formatString(b []byte, s string) {
	if len(s) > len(b) {
		f.err = ErrFieldTooLong
	}
	copy(b, s)
	if len(s) < len(b) {
		b[len(s)] = 0
	}

# KMS IAM/Config Encryption

MinIO supports encrypting config, IAM assets with KMS provided keys. If the KMS is not enabled, MinIO will store the config, IAM data as plain text erasure coded in its backend.

## MinIO KMS Quick Start

MinIO supports two ways of encrypting IAM and configuration data.
You can either use KES - together with an external KMS - or, much simpler,

## Decoding Metadata

Metadata is stored in `xl.meta` files for erasure coded objects. Each disk in the set containing the object has this file. The file format is a binary format and therefore requires tools to view values.
