# Install the Disaster Recovery backup agent for Windows

## Prerequisites

DR backup agent supports the following Windows versions:

• Windows 7 SP1 or later

• Windows Server 2008 R2 SP1 or later

For proper operation of the DR backup agent, make sure to install the following software on the client:

Starting from IBDR 8.7, to establish connection between the protected client and the CFA, you must enable NTLMv2 authentication on the client.

On the clients running Windows 7 SP1 or Windows Server 2008 R2 SP1, the following Windows updates must be installed:

• KB2999226

• KB3033929

• KB3035131

On the clients running Windows 8 or Windows Server 2012 R2, or later, the following Windows updates must be installed:

• KB2919355

• KB2919442

• KB2999226

## Regular installation

On the Windows client you want to back up:

After the backup agent is installed, it gets into the Waiting for pairing state, and waits 24 hours to receive the settings (password and port) from the CFA to establish connection.

For details on how to connect the DR backup agent with CFA, see Pair with appliance.

## Silent installation

Backup agent installer supports the silent mode, that is when the installation runs in the background and does not require user interaction.

To install the backup agent on a client silently:

1. Open Command Prompt.

2. Enter path-to-installer -quiet, where path-to-installer is the path to the backup agent installer.

For example:

C:\Users\Default\Downloads\backup-client-8.5.0.104.Win32.x64.exe -quiet


## Run 32-bit and 64-bit versions on one system

1. Add two clients for the same machine you want to back up.

2. In the CFA Management Console, go to ClientsEdit.

1. Select one of the newly added clients.

2. In the Client Networking group, set the port to 9101.

3. Click to save changes.

4. Click so the changes take effect.

This client will use the 32-bit version of the backup agent to pair with the CFA.

The other one will use the 64-bit version of the backup agent to pair with the CFA using the default port 9102.

3. Set up the 32-bit version of the backup agent:

1. Install and run the 32-bit version of the backup agent on the client with port 9102.

You can find the configuration utility (RVXConfig.exe) for the 32-bit version of the backup agent in C:\Program Files (x86)\RVX-Backup.

2. On the Appliance tab, select Manually Assign Appliance Information, enter the port 9101, and then click .

4. In the CFA Management Console:

1. Go to ClientsEdit.

2. Select the client where you installed the 32-bit backup agent.

3. In the General group, click .

It takes a few minutes for the backup agent and the CFA to connect.

You can verify that the client is paired with the CFA using the 32-bit version of the backup agent in the CFA Management Console › ClientsSummary.

5. Set up the 64-bit version of the backup agent:

1. Install the 64-bit version of the backup agent on another newly added client.

2. In the CFA Management Console, go to ClientsEdit.

3. Select the client where you installed the 64-bit backup agent.

4. In the General group, click .

It takes a few minutes for the backup agent and the CFA to connect.

You can verify that the client is paired with the CFA using both the 32-bit and 64-bit versions of the backup agent in the CFA Management Console (ClientsSummary.)
