# Installing the Backup Role
TIP
We recommend installing the backup role on a completely separate server to your web servers and hosting it in a different data centre
Prerequisites: Prior to installing the backup role:
- If using an external firewall, ensure ports 50000 and 22 are permitted from every server in your cluster.
- Ensure your server has adequate disk space for the websites you wish to back up.
To add a backup role to a server:
- Click Servers in the left side bar
- Choose the server that you want to add the backup role to
- Click Add role and select the Backup check box.
- Choose a directive with adequate space to store your website backups, click
Add Role
.
TIP
If you have websites which were created before the backup role was installed, you may wish to map them to the new backup server using the move server option in the left hand menu.
