The Synology NAS is a very user-friendly storage system for private persons and small to medium businesses. It comes with a large number of applications and can synchronize with an Amazon S3-compatible storage like the Exoscale Object Storage. This guide shows how to set that up with the Cloud Sync application.


This method synchronizes the Synology NAS with the Exoscale Object Storage. It does not create a versioned backup. If you want to create a versioned backup please use Hyper Backup.


As prerequisite for the following documentation, you’ll have to:

Install Cloud Sync

Please open the Package Center:


Search for and install Cloud Sync (created by Synology Inc.):

Set up Cloud Sync

Open the main menu and start Cloud Sync. Then follow the figures.

When asked for account settings, select Customer Server URL and enter in the server field, taking care of substituting ZONE with the proper zone. Also insert your IAM-Key, secret and bucket name there.


You can find all Zones on our website and with the cli: exo zones list
