## Description of `xl.meta`

`xl.meta` is a new self describing backend format used by MinIO to support AWS S3 compatible versioning.
This file is the source of truth for each `version` at rest. `xl.meta` is a msgpack file serialized from a

See our web documentation on [Deploying MinIO in Standalone Mode](Deploy Standalone MinIO in a Container) for a more structured tutorial on deploying MinIO in a container.

## Prerequisites

# Bucket Lifecycle Configuration Quickstart Guide [![Slack](https://slack.min.io/slack?type=svg)](https://slack.min.io) [![Docker Pulls](https://img.shields.io/docker/pulls/minio/minio.svg?maxAge=604800)](https://hub.docker.com/r/minio/minio/)

Enable object lifecycle configuration on buckets to setup automatic deletion of objects after a specified number of days or a specified date.

## 1. Prerequisites

- [Deploy a Tenant from the MinIO Operator](https://min.io/docs/minio/kubernetes/upstream/operations/install-deploy-manage/deploy-minio-tenant.html)

Install Distributed MinIO on Linux:
- [Deploy Distributed MinIO on Linux](https://min.io/docs/minio/linux/operations/install-deploy-manage/deploy-minio-multi-node-multi-drive.html#deploy-distributed-minio)

### 2. Run distributed MinIO

## HTTP Trace

HTTP tracing can be enabled by using [`mc admin trace`](https://github.com/minio/mc/blob/master/docs/minio-admin-complete-guide.md#command-trace---display-minio-server-http-trace) command.

Example:

```sh
minio server /data

Bucket replication is designed to replicate selected objects in a bucket to a destination bucket.
