In this article, we’ll cover how to secure the R1Soft Server Backup Manager (CDP) with Let’s Encrypt SSL.

Here is what the script does :

• Updates the following packages:
  nss nss-util nss-util nss-sysinit nss-tools wget  curl  ca-certificates openssl

• Downloads Certbot (if not already done)

• Creates a Keystore for R1Soft CDP

• Creates a Let’s Encrypt certificate through Certbot

• Imports the certificate into R1Soft Keystore

First, we need to change the CDP webserver port:

Once done, you’ll access the R1Soft Server Backup Manager via https://your.backupserver.com:6443/

Now, simply wget the script, change execution rights, and launch it:

You can add a cron to renew your certificate:

You can also clone this git repo, and create a cron task to get the script updates:

Script update cron:

You just have to make sure your web ports are not filtered, and nothing is running on port 80 (or you’ll have to stop it before launching the script).

As above, R1Soft runs only on port 6443, therefore leaving ports 80 and 443 available.

Solution:

That’s it!

You can now access your R1Soft Server Backup Manager over SSL: https://your.backupserver.com:6443/
