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/"
            },

### 2. Set bucket WORM configuration

WORM on a bucket is enabled by setting object lock configuration. This configuration is applied to all the objects in the bucket. Below is an example to set `Governance` mode and one day retention time on `mybucket`.

```sh
awscli s3api put-object-lock-configuration --bucket mybucket --object-lock-configuration 'ObjectLockEnabled=\"Enabled\",Rule={DefaultRetention={Mode=\"GOVERNANCE\",Days=1}}'
```

The Prometheus endpoint in MinIO requires authentication by default. Prometheus supports a bearer token approach to authenticate prometheus scrape requests, override the default Prometheus config with the one generated using mc. To generate a Prometheus config for an alias, use [mc](https://min.io/docs/minio/linux/reference/minio-mc.html#quickstart) as follows `mc admin prometheus generate <alias> [METRIC-TYPE]`. The valid values for METRIC-TYPE are `cluster`,...

```

Description of the configuration parameters used above -

- `buckets[].name` - name of the bucket to create, must be a string with length > 0
- `buckets[].policy` - can be one of none|download|upload|public
- `buckets[].purge` - purge if bucket exists already

### Create policies after install

Install the chart, specifying the policies you want to create after install:

```bash

The following Bucket features will **not be replicated**, is designed to differ between sites:

- Bucket notification configuration
- Bucket lifecycle (ILM) configuration

## Pre-requisites

unlike RAID or replication. For example, RAID6 can protect against two drive failure whereas in MinIO erasure code you can lose as many as half of drives and still the data remains safe. Further, MinIO's erasure code is at the object level and can heal one object at a time. For RAID, healing can be done only at the volume level which translates into high downtime. As MinIO encodes each object individually, it can heal objects incrementally. Storage servers once deployed should not require drive replacement...

3. [Cloud Scale Deployment](#cloud-scale-deployment)

## 1. Standalone Deployment

To host multiple tenants on a single machine, run one MinIO Server per tenant with a dedicated HTTPS port, configuration, and data directory.

### 1.1 Host Multiple Tenants on a Single Drive

Use the following commands to host 3 tenants on a single drive:

```sh

MinIO versioning is designed to keep multiple versions of an object 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.

points to the public IP address where each cluster might be accessible, this is unique for each cluster.

NOTE: `mybucket` only exists on one cluster either `cluster1` or `cluster2` this is random and
is decided by how `domain.com` gets resolved, if there is a round-robin DNS on `domain.com` then
it is randomized which cluster might provision the bucket.

## Prerequisites

- One or both of Veeam Backup and Replication with support for S3 compatible object store (e.g. 9.5.4) and Veeam Backup for Office365 (VBO)
- MinIO object storage set up per <https://min.io/docs/minio/linux/index.html>
