How to Backup your Data with Snapshots

Snapshot Overview

A snapshot is a full-volume copy of your server and its data. Snapshots are perfect if you want to recover a server from a previous state. They are stored in our secure data centers.

Potential uses:

  • Recover volume data
  • Create a copy from a volume

Requirements

Archiving a Server (Recommended)

Note: To ensure data integrity, Scaleway recommends archiving your server prior to taking a snapshot. However, the Hot Snapshots option is also available on Virtual Cloud Servers, if you prefer no to stop your server.

In the Compute section, select a server from which you want to make a snapshot. Note that the server must be archived beforehand. To archive a running server you have two options:

Option 1: On the server list page, use the dropdown menu next to a server to select Archive.

Option 2: On a server overview page, scroll down to the Archive Server section and click Archive Server.

Once your server is archived you can snapshot your volumes.
