## 3. Activate ILM versioning features
This will only work with a versioned bucket, take a look at [Bucket Versioning Guide](https://docs.min.io/docs/minio-bucket-versioning-guide.html) for more understanding.
### 3.1 Automatic removal of non current objects versions
A non-current object version is a version which is not the latest for a given object. It is possible to set up an automatic removal of non-current versions when a version becomes older than a given number of days.
e.g., To scan objects stored under `user-uploads/` prefix and remove versions older than one year.
```
{
"Rules": [
{
"ID": "Removing all old versions",
"Filter": {
"Prefix": "users-uploads/"
},
"NoncurrentVersionExpiration": {
"NoncurrentDays": 365
},
"Status": "Enabled"
}
]
}
```
### 3.2 Automatic removal of delete markers with no other versions
When an object has only one version as a delete marker, the latter can be automatically removed after a certain number of days using the following configuration:
```
{
"Rules": [
{
"ID": "Removing all old versions",
"Expiration": {
"Days": 1,
"ExpiredObjectDeleteMarker": true
},
"Status": "Enabled"
}
]
}
```
