# Bucket Replication 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/)

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

### Per-bucket Metrics

Metrics with a `/bucket` component in the path return results for each specified bucket in the deployment. These endpoints **require** providing a list of buckets as a `bucket` query parameter.  The endpoint then returns only metrics for the given buckets, with the bucket name in a `bucket` label.
