# Back up a Synology NAS

{{< recipes-disclaimer >}}

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 create backups to an Amazon S3-compatible storage like Exoscale Simple Object
Storage. This guide shows how to set up backups to SOS with the Hyper Backup
application.

This method creates a versioned backup of a Synology NAS to the Exoscale Object Storage.

## Prerequisites

Before you start this guide, you will need to:

- Create a SOS Bucket, either via the [Portal](https://portal.exoscale.com/) or
the [CLI]({{< ref "/tools/command-line-interface/" >}}).
See the [Simple Object Storage documentation]({{< ref "/product/storage/object-storage/quick-start/" >}})
for more information.

- Create an IAM key, also via the Portal or the CLI. See the
[IAM documentation]({{< ref "/product/security/iam/quick-start/" >}})
for more information.
