Migrating Object Storage data with Minio Client

Minio Client Overview

Minio Client provides a modern alternative to UNIX commands like ls, cat, cp, mirror, diff etc. It is able to communicate with any S3 compatible cloud storage provider and can be used to migrate data from one region to another.

Requirements

Installing the Minio Client

1 . Connect to your server as root via SSH.

2 . Update the APT packet cache and the software already installed on the instance:

apt update && apt upgrade -y

3 . Download the Minio Client:

wget https://dl.minio.io/client/mc/release/linux-amd64/mc -P /usr/bin/

4 . Make the file executable:

chmod +x /usr/bin/mc

Configuring the Minio Client and Migrating Data

1 . Configure the endpoints you wish to use

mc config host add scw-fr-par https://s3.fr-par.scw.cloud <ACCESS_KEY> <SECRET_KEY> --api S3v4
mc config host add scw-nl-ams https://s3.nl-ams.scw.cloud <ACCESS_KEY> <SECRET_KEY> --api S3v4

Important: Replace <ACCESS_KEY> and <SECRET_KEY> with the credentials of your API token.

2 . Add other providers if you wish

For S3 compatible storages :

mc config host add s3 <ENDPOINT> <OTHER_ACCESS_KEY> <OTHER_SECRET_KEY> --api S3v4

For google cloud storage :

mc config host add gcs  https://storage.googleapis.com <ACCESS_KEY> <SECRET_KEY> --api S3v2

3 . Create the buckets you need on the scaleway object storage

mc mb --region fr-par scw-fr-par/<BUCKET_NAME>
mc mb --region nl-ams scw-nl-ams/<OTHER_BUCKET_NAME>

4 . Start the migration of your data:

mc cp --recursive s3/<BUCKET_NAME> scw-fr-par/<BUCKET_NAME>
mc cp --recursive gcs/<OTTHER_BUCKET_NAME> scw-nl-ams/<OTHER_BUCKET_NAME>

The above commands :

  1. migrates data from a S3 compatible object storage to Scaleway’s fr-par object storage
  2. migrates data from GCS object storage to Scaleway’s nl-ams object storage

Please note that this migration can incur some cost from the object storage you are migrating from since they may or may not bill egress bandwitdth.

Minio Client displays a status bar during the transfer, allowing to observe the status of the migration:
