This article describes how to install and activate a NAS proxy through the Hybrid Workloads Management Console. Registering a NAS Proxy is the first step towards configuring Druva to back up a NAS share. Registering a NAS proxy involves:

  1. Installing a NAS proxy
  2. Activating the NAS proxy
  3. Configure Web proxy

Considerations for adding a NAS proxy

Druva supports backups of SMB and NFS shares.  Install the NAS proxy on:

  • A Windows server to back up SMB shares.
  • A Linux server to back up NFS shares.

Step 1: Installing a NAS proxy

  1. Log in to the Hybrid Workloads Management Console.
  2. Select the workload from the Protect menu. Note that if the All Organizations menu is enabled, you have to first select an organization where you want to add the NAS proxy, and then select the workload.
  3. The Get Started page is displayed if no NAS devices have been configured so far. On the Get Started page, under Register a NAS proxy, you will see No Proxy Registered. Click Add Proxy.

  5. Depending upon the type of share that you want to back up, download the agent on the Windows/Linux server that will act as the NAS proxy.
    Note: Using this Hybrid Workloads agent, you can protect MS SQL, File Servers, and Hyper-V workloads on a Windows Server or Linux Server. For more information, see Common agent installation and activation.
    Share Type Download and install the following agent on the server
    SMB Windows 64-bit agent on the Windows server
    NFS Linux or Ubuntu agent on the Linux/Ubuntu server

Installing the NAS proxy on a Windows server

The NAS proxy handles the backup and restore of NAS shares. Install the NAS proxy on a Windows server if you want to back up SMB shares.  

  1. Log in as an administrator on the Windows server where you want to install the NAS proxy. 
  2. Navigate to the location where you've downloaded the NAS proxy installer. 
  3. Double-click the NAS proxy installer and on the Welcome screen click Next. 
  4. Accept the terms in the license agreement and privacy policy, and click Next. 
  5. Use the local system account for installing the agent. 
  6. In the Install location box, type the install path or browse to the installation home directory. 
  7. Click Install. After the installation completes, click Finish.

Command-line install:

Run the following command from the command prompt

msiexec /i <path to Phoenix msi> /qn /quiet /log <path to log file>

For example:
msiexec.exe/i C:\Users\Administrator\Downloads\Phoenix-6.0.1-154609.msi /qn/quiet/log C:\Users\Administrator\Downloads

Installing the NAS proxy on a Linux server

The NAS proxy handles the backup and restore of NAS shares. Install the NAS proxy on a Linux server if you want to back up NFS shares.

  1. Log in as the root user on the Linux server where you want to install the NAS proxy.
  2. Navigate to the location where you've downloaded the NAS proxy installer.
  3. Run the following command depending on the OS of the server
    Operating System Command
    RHEL, CentOS, or SLES rpm –ivh <package name>
    Where <package name> is the installer name with its extension.
    Ubuntu

    dpkg –i <package name>

    Where <package name> is the installer name with its extension.
     

Step 2: Activating the NAS proxy  

After you install the NAS proxy, you must activate it using the activation token generated on the Hybrid Workloads Management Console at the time of adding the proxy. The token functions as a unique identifier and performs a one-time authentication of the NAS proxy. After activation, the NAS proxy establishes a persistent connection with Druva Cloud. 

Note: If your network infrastructure uses a Web proxy, you must configure it before activation. For more information, see Configure {{webproxy}}.

Activating the NAS proxy on a Windows Server

  1. In the Add NAS Proxy wizard, under the Activate Proxy section, select a valid activation token. An activation token can be used to activate up to 25 NAS proxies and expires in 7 days. If all activation tokens have expired, Druva creates a Default Activation Token automatically when you click Add Proxy.  If you want to create a new token, perform the following tasks:

    1. Click Generate New Token to create a new token. 
    2. In the Generate Token dialog box, enter the following details, and click Generate.
      Generate token.png
       
    3. In the Generate Token dialog box, click Done.
    4. Select the newly generated token from the drop-down list under Activation Token.
    5. In the Activate Proxy section, under Windows Server, click Copy Command to copy the activation command.
      Downloadspage_NAS_cptkn.png
  2. On the Windows server, open the command prompt.
    Note: If you are using an agent older than version 6.0.1-154928,  navigate to C:\Program Files\Druva\Phoenix Agent .
  3. Paste the command and press Enter. You can also append the server name by editing the command:
    • For Druva Cloud: 
      HybridWorkloadsAgent.exe nas activate -t <token> -n <ProxyName>

      For example: 
HybridWorkloadsAgent.exe nas activate -t 67831-228-1762-591132241ce4fb2e14fca792cbf532f4a2359eb0bf1b96f82211373ebea7c23b -n WIN-RTG3
      Note: If you are using an agent older than version 6.0.1-154928, the following command can be used:
      PhoenixNasControl.exe activate <activation token>

where <token> represents the activation token that Druva generated at the time of registering server.

  • For GovCloud: 
    HybridWorkloadsAgent.exe nas activate –g -t <token> -n <ProxyName>

    For example:
HybridWorkloadsAgent.exe nas activate -g -t 67831-228-1762-591132241ce4fb2e14fca792cbf532f4a2359eb0bf1b96f82211373ebea7c23b -n WIN-RTG3
Note: If you are using an agent older than version 6.0.1-154928, the following command can be used:
PhoenixNasControl.exe activate govcloud <activation token>
Field  Description
token
(-t, --token string)

Paste the copied activation.

Note: This is the token copied from the Add NAS Proxy dialog box.
ProxyName
(-n, --ServerDisplayName string)		 Enter a unique proxy name in the current Organization for each workload of the same type.
GovCloud
( -g, --gov-cloud)		 Enable GovCloud.

In both the above commands, <activation token> is the activation token of the NAS proxy. 

The NAS proxy name is not case sensitive. You cannot have one NAS proxy registered as "ABC" and another as "abc". Druva will display the error message "Server display name already exists. Cannot register the server with same display name."

 

  1. If you’re using the Hybrid Workloads Agent shortcut to activate the agent, click Copy Token.
    1. Double-click the Hybrid Workloads Agent shortcut on the Windows server where the Hybrid Workloads Agent needs to be activated.

        Note: If you are using an agent older than version 6.0.1-155102, the following command can be used:
        PhoenixNasControl activate <activation token>

      • GovCloud

        HybridWorkloadsAgent nas activate –g -t <token> -n <ProxyName>

        For example:
HybridWorkloadsAgent nas activate -g -t 67831-228-1762-591132241ce4fb2e14fca792cbf532f4a2359eb0bf1b96f82211373ebea7c23b -n WIN-RTG3
        Note: If you are using an agent older than version 6.0.1-155102, the following command can be used: 
        PhoenixNasControl activate govcloud <activation token>

In both the above commands, <activation token> is the activation token of the NAS proxy. 

The NAS proxy name is not case sensitive. You cannot have one NAS proxy registered as "ABC" and another as "abc". Druva will display the error message "Server display name already exists. Cannot register the server with same display name."
