# HYCU Backup

This guide is provided for informational purposes. Because it involves third party tooling we cannot guarantee things still work exactly as described here.

The backup software HYCU is popular in the enterprise area. Amazon
S3-compatible object storage can be used as long-term storage. Exoscale offers
such S3-compatible storage, which is perfect for HYCU. This guide shows you how
to set up HYCU to use the Exoscale Simple 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](https://community.exoscale.com/tools/command-line-interface/index.md).
See the [Simple Object Storage documentation](https://community.exoscale.com/product/storage/object-storage/quick-start/index.md)
for more information.

- Create an IAM key, also via the Portal or the CLI. See the [IAM documentation](https://community.exoscale.com/product/security/iam/quick-start/index.md) for more information.

## Add an S3 Bucket as a Backup Target

Log into the HYCU portal:

Click on *Targets* in the main navigation. In the Targets view, click *Add*.

Enter a name. You can also enter an optional description.

Select the **AWS S3/Compatible** type and enter the service endpoint (Such as https://sos-de-muc-1.exo.io).

Then enter the bucket name and login information.

There are additional parameters which can be adjusted, such as the size (or quota), compression, or encryption before you upload.

Depending on where the bucket has been created, you will have to enter the
appropriate service endpoint. The endpoint is `https://sos-ZONE.exo.io`. Make sure
to substitute `ZONE` with the relevant zone.

> You can find all Exoscale zones on
> [our website](https://www.exoscale.com/datacenters/) 
> or with the CLI command: `exo zones list`.
