Migrating Scaleway Object Storage data with Rclone

Reviewed on 23 September 2024Published on 20 March 2019
  • Rclone
  • object-storage

Rclone provides a modern alternative to rsync. The tool communicates with any S3-compatible cloud storage provider as well as other storage platforms and can be used to migrate data from one bucket to another, even if those buckets are in different regions.

Before you start

To complete the actions presented below, you must have:

  • A Scaleway account logged into the console
  • Owner status or IAM permissions allowing you to perform actions in the intended Organization
  • An SSH key
  • A valid API key
  • An Instance running on Ubuntu Focal Fossa
  • At least 2 Object Storage buckets

Installing Rclone

  1. Connect to your server as root via SSH.
  2. Update the APT package cache and the software already installed on the Instance.
    apt update && apt upgrade -y
  3. Download and install Rclone with the following sequence of commands:
    wget https://downloads.rclone.org/rclone-current-linux-amd64.zip
    apt install zip
    unzip rclone-current-linux-amd64.zip
    cd rclone*linux-amd64/
    mv rclone /usr/bin/

Configuring Rclone

  1. Begin Rclone configuration with the following command:

    rclone config

    If you do not have any existing remotes, the following output displays:

    2021/01/18 16:03:28 NOTICE: Config file "/root/.config/rclone/rclone.conf" not found - using defaults
    No remotes found - make a new one
    n) New remote
    s) Set configuration password
    q) Quit config

    If you have previously configured rclone you may see a slightly different output. However, that does not affect the following steps.

  2. Type n to make a new remote. You are then prompted to type a name - here we type remote-sw-paris:

    n/s/q> n
    name> remote-sw-paris

    The following output displays:

Note

If you want to be able to transfer data to or from a bucket in a different region than the one you just set up, repeat steps 1-14 to set up a new remote in the required region. Simply enter the required region in steps 7 and 8. Similarly, you may wish to set up a new remote for a different Object Storage provider.

Migrating data

Two commands can be used to migrate data from one backend to another.

  • The copy command copies data from source to destination.
rclone copy --progress <SOURCE_BACKEND>:<SOURCE_PATH> <DEST_BACKEND>:<DEST_PATH>

For example, the following command copies data from a bucket named my-first-bucket in the remote-sw-paris remote backend that we previously set up, to another bucket named my-second-bucket in the same remote backend. The --progress flag allows us to follow the progress of the transfer:

rclone copy --progress remote-sw-paris:my-first-bucket remote-sw-paris:my-second-bucket
  • The sync command copies data from one backend to another, but also deletes objects in the destination that are not present in the source:
rclone sync --progress <SOURCE_BACKEND>:<SOURCE_PATH> <DEST_BACKEND>:<DEST_PATH>

The following command copies data from a bucket named my-first-bucket in the remote-sw-paris remote backend that we previously set up, to another bucket named my-third-bucket in a different remote backend that we configured for the nl-ams region and named remote-sw-ams. It also deletes any data present in my-third-bucket that isn’t also present in my-first-bucket:

rclone sync --progress remote-sw-paris:my-first-bucket remote-sw-ams:my-third-bucket
Note

This migration may incur costs from the Object Storage tool you are migrating from since they may or may not bill egress bandwidth.

For further information, and to discover other commands available, refer to the official RClone S3 Object Storage Documentation.

Transferring data to Scaleway Glacier

When you copy or sync, you can determine which storage class you wish to transfer your data to.

At Scaleway you can choose from two classes:

  • STANDARD: The Standard class for any upload; suitable for on-demand content like streaming or CDN.
  • GLACIER: Archived, long-term retention storage.

If the storage class is not specified, the data will be transferred as STANDARD by default.

To transfer data to Scaleway Glacier class, add --s3-storage-class=GLACIER to your command, as such:

rclone copy --progress --s3-storage-class=GLACIER <SOURCE_BACKEND>:<SOURCE_PATH> <DEST_BACKEND>:<DEST_PATH>

You can verify the storage class of the transferred data by accessing your bucket on the Scaleway console.
