This guide details the process of installing the Acronis Backup Agent on a Windows Server.

To complete the guide, you’ll need to access your server’s Desktop remotely. For this, we recommend Microsoft Remote Desktop or remote console.

If you’d like to learn how to access your server via the remote console, read the following guide:
How to access IPMI / Remote Console

Adding a Protection Plan

Before we can start, your Acronis Cyber Protect tenant requires at least ONE valid Protection Plan.

Additionally, we strongly recommend cloning and using a separate Protection Plan for each protected workload, as any changes made to a multi-use plan will affect all workloads protected by that plan.

You can find a list of Protection Plan templates at the linked page. Make sure to select a “Standard Backups” plan.

Protection Plan templates

A guide showing how to import the downloaded Protection Plan file is linked below:

How to import a Protection Plan


A guide showing how to clone the imported Protection Plan can be found further down in the same guide:
Cloning a Protection Plan

If you already have a suitable Protection Plan, you may continue to the next section:
Allowing Acronis IPs into the firewall

Allowing Acronis IPs into the firewall

For Acronis Backups to function, you’ll need to allow the following IP addresses through Windows Server’s firewall.

45.11.129.61
45.11.129.62
45.254.37.11
45.254.37.12
45.254.37.13
45.254.37.14
45.254.37.15
45.254.37.16
45.254.37.17
45.254.37.18
45.254.37.19
45.254.37.20
103.101.129.51
103.101.129.52
117.120.8.238


If you are using Windows Firewall, you can complete this quickly by pasting this pre-made command into a PowerShell window on your server:

New-NetFirewallRule -DisplayName 'SAU Acronis Infrastructure Allow Inbound' -Group 'SAU Acronis Backups' -Direction Inbound -Action Allow -Enabled True -Profile Any -Protocol Any -RemoteAddress "45.11.129.61-45.11.129.62","45.254.37.11-45.254.37.20","103.101.129.51-103.101.129.52","103.64.16.0/24" -EdgeTraversalPolicy Block; New-NetFirewallRule -DisplayName 'SAU Acronis Infrastructure Allow Outbound' -Group 'SAU Acronis Backups' -Direction Outbound -Action Allow -Enabled True -Profile Any -Protocol Any -RemoteAddress "45.11.129.61-45.11.129.62","45.254.37.11-45.254.37.20","103.101.129.51-103.101.129.52","103.64.16.0/24" -EdgeTraversalPolicy Block; New-NetFirewallRule -DisplayName 'SAU Acronis syd-gateway Allow Outbound' -Group 'SAU Acronis Backups' -Direction Outbound -Action Allow -Enabled True -Profile Any -Protocol Any -RemoteAddress "117.120.8.238" -EdgeTraversalPolicy Block

This command will create three separate Windows Firewall rules (one inbound,  two outbound). These are locked down to only allow traffic relevant to Acronis.

If your SAU server is protected by a FortiGate Firewall, please refer to the below drop-down to see how to easily allow these IP addresses:

How to whitelist Acronis IPs on a FortiGate Firewall

  1. Log into your FortiGate web UI.

  2. Copy and paste the below code block into the FortiGate CLI.
    These commands will create Acronis address objects, and combine these objects into an Address Group.

config firewall address
    edit "Acronis 45.11.129.61/31"
        set subnet 45.11.129.61 255.255.255.254

    edit "Acronis 45.254.37.11/32"
        set subnet 45.254.37.11 255.255.255.252

        set subnet 45.254.37.16 255.255.255.254

        set subnet 117.120.8.238 255.255.255.255
    next
end

config firewall addrgrp
    edit "Acronis IP Group"
        append member "Acronis 45.11.129.61/31"
        append member "Acronis 45.254.37.11/32"

        append member "Acronis 45.254.37.18/31"
        append member "Acronis 45.254.37.20/32"
        append member "Acronis 103.64.16.0/24"
        append member "Acronis 103.101.129.51/31"
        append member "Acronis 117.120.8.238/32"
    next
end

  1. In your Firewall Policy table, create a WAN > LAN ACCEPT policy that matches the below image. “Acronis IP Group” will already exist if you ran the commands in the previous step.

Downloading the Agent installer

  1. Log in to the Acronis Cyber Protect Cloud portal, found here:
    https://backup.aci.servercontrol.com.au/login

    The default tenant username can be found in the MySAU portal, as shown in this guide:
    How to access the Acronis Cyber Protect Cloud portal

  1. Click “Devices”.

  2. Click the “Add” button in the top-right.

  3. Under “Servers”, click “Windows” to download the Acronis Windows agent.

  4. Once the agent executable has downloaded, access your server with RDP and upload the executable to the server by copying and pasting it in a folder.
    If you have a different, preferred way to copy a file to your server, you may use that instead.

Installing and registering the Acronis agent

R1Soft Agent removal

If your server previously made use of our legacy R1Soft backup solution, you’ll need to uninstall it before installing Acronis.
Click the below drop-down to see a guide on how to complete this:

How to uninstall the R1Soft Agent

  1. Navigate to “Programs & Features”
    You can access this via Control Panel, or by entering “    appwiz.cpl“ into Run or the Start Menu.

  2. Give the program list some time to load. Once completed, find “Server Backup Agent” and click it.

  3. Click “Uninstall”.

  4. Click “Yes”.

    Wait for the uninstallation to complete.

  5. Click “No”.
    Please note that the removal of R1Soft does NOT require an immediate restart.

  6. Continue through the guide as normal.

If you don’t have R1Soft installed, continue on.

  1. On your Windows Server, run the installer program you previously copied over.
    In this example, the program was copied to Downloads.

  2. Click “Install”.

    Wait for the agent to download and install.

  3. Once the agent has installed, click “Show registration info”

  4. Copy the registration code.

  5. Back in your browser, navigate to Devices » Add, and scroll down on the right sidebar.



  6. Click “Register”.

  7. In the registration wizard, complete the following:

    1. Paste the registration code.

    2. Select your user. The example used here is “John Smith”.

    3. Click “Validate code” to confirm connectivity from the server to the Acronis Cloud.

    4. Click “Next”.

  8. Ensure that your preferred protection plan is selected.

    Leave all other plan types unselected.

    Click “Next”.

  9. Click “Register”.

  10. After a short moment, the server should appear in the list of devices. You may need to refresh the page.

  11. Returning to your Windows Server, the installer should display the following:

Acronis agent setup is complete!
