To back up your virtual machines, you must first download and install a backup proxy in your virtual infrastructure environment and then register it from the Management Console. This article describes how to get the backup proxy and activation token and register your servers.

Download OVA to deploy VMware proxy

Download the latest version of the backup proxy from the following location:

Druva Downloads page

Go to http://downloads.druva.com/phoenix/. From the Select Agent drop-down list select VMware.

Register VMware setup wizard

Perform the following steps to download the backup proxy from the Register VMware setup:

Log in to the Management Console.
Select the workload from the Protect menu. Note that if the All Organizations menu is enabled, you have to first select an organization and then select the workload.
Download the appropriate installer to deploy the VMware backup proxy.

Ensure that you download the correct backup proxy from the Downloads page. To register a standalone ESXi server, download the standalone backup proxy. To register a vCenter server, download the vCenter backup proxy.

Select your cloud type as Public Cloud or GovCloud and then download OVA. The following table describes the OVA and packages on the Downloads page.

OVA/Package	Description
Druva Proxy Deployer	Use this proxy deployer tool to deploy the first backup proxy
VMware (Ubuntu Backup Proxy for vCenter)	OVA to deploy proxy on vCenter
VMware (Ubuntu Backup Proxy for standalone ESXi)	OVA to deploy proxy on standalone ESXi host
VMware (Backup Proxy DEB Package)	DEB package to manually upgrade the Ubuntu backup proxy
VMware (RPM for Backup Proxy Upgrade)	RPM package to manually upgrade the CentOS backup proxy

Generate activation token

To register your VMware set up, an activation token is required. Perform the following to generate an activation token.

Log in to the Management Console.
From the top menu bar, select your organization if organizations are enabled. Otherwise, proceed to the next step.
Click Protect > VMware.
Click Register.
From the Register New VMware Setup dialog box, select the Copy Token icon under the Activate Backup Proxy section. The activation token is copied successfully.

This token is valid for 25 servers and 7 days. This is required for connecting with the Druva Cloud during proxy deployment.

📝 Note
If this token has expired, click Generate New Token. Enter the required details in the Generate Token dialog box and click Generate. Alternatively, if you have generated an activation token earlier, you can copy it from the Manage Activation Tokens page.

Register vCenter using web client

Before you begin

Before you begin, ensure the following:

You have the following information:
- vCenter credentials
- Web proxy credentials (If you use a Web proxy in your environment).
- Activation token. For more information, see Generate activation token.
- IP settings.

📝 Note
This process of deploying and configuring the backup proxy using a web client is applicable only for a vCenter host. vCenter has the capability to temporarily store the parameters received during the OVF deployment. For additional help on deploying OVF templates, see the associated VMware documentation depending on the version of your VMware setup. For example, see this article from the vSphere 5 documentation library. You can deploy a backup proxy on a vCenter server whose virtual machines you want to back up. If you have not deployed the vCenter Server, you can deploy a backup proxy on a standalone ESXi host. See, Register a standalone ESXi
You must deploy backup proxy on the same vCenter Server or the ESXi host from where virtual machines are to be backed up. If you use an HTML5 web client for proxy deployment, you'd need to enter 'j.proxy type' in the HTTP field under Web Proxy Settings as a hard value, even if there is no web proxy. The proxy will not power on post-deployment without this value.

Deploy backup proxy

Log into vSphere Web Client.
In the left pane, select the host under Hosts and Clusters.
In the right pane, click Actions and select Deploy OVF Template.
Select an OVF template from the remote URL or local file system
Specify a unique name and target location of the virtual machine.
Select the destination compute resource for this operation.
Verify the template details, and click Next.
Click I accept all license agreements and click Next.
Select the storage for the configuration and disk files. You can select the virtual disk format and VM Storage Policy.

You can select from the below provisioning formats:
- Thick Provisioned Lazy Zeroed: If you select this format, a thick virtual disk is created, and the existing data is lazy zeroed (existing data on the provisioned storage are cleared when the virtual machine writes to the storage for the first time).
- Thick Provisioned Eager Zeroed: If you select this format, a thick virtual disk is created, and the existing data is eager zeroed (existing data on the provisioned storage is overwritten with zeroes at the time of creating the virtual machine).
- Thin Provisioned: If you select this format, a thin virtual disk is created.
Select a destination network for each source network, and click Next.

Review your settings selection before finishing the wizard.

Before configuring the backup proxy, ensure that:

You have the ESXi root credentials handy. You can either set the fully qualified domain name (FQDN) or the IP address of ESXi Server.

📝 Note
Backup proxy stores these credentials in an encrypted format.
Ensure port 443 on ESXi host is configured for http/https traffic. ESXi host is configured for http/https traffic. The backup proxy communicates with the registered ESXi host on port 443.

📝 Note
You can configure backup proxy settings for Standalone ESXi only through CLI. The process of configuring backup proxy through vCenter is applicable only through vCenter web client and not in the case of standalone ESXi because vCenter has the capability to temporarily store the parameters received during the OVF deployment.

How to configure or reconfigure backup proxy

If your VMware backup proxy is not activated using the above method, you can manually activate and configure it by running the ProxyConf command in the proxy CLI. The ProxyConf utility can be found at /opt/Druva/EnterpriseWorkloads/bin/ProxyConf.

From the vSphere Client console, start the backup proxy virtual machine. Alternatively, if you know the IP address of the proxy VM, you can log in to it from any CLI using the credentials provided in the note below.
Log on to the virtual machine with the username and password.

📝 Note
After you reset the default password of the backup proxy virtual machine, the ProxyConf utility available at /opt/Druva/Phoenix/bin/ is invoked. The ProxyConf utility prompts you for inputs while performing tasks 4 through 6, thus completing the backup proxy configuration.

Perform a standalone activation of backup proxy

If your VMware backup proxy is not activated or if you want to activate the backup proxy at a later stage, use the following steps for activation:

From the vSphere Client console, click VMs and Templates, and start the backup proxy virtual machine.
Log on to the virtual machine with the default username and the changed password.
Run the following command to activate the backup proxy:
- PhoenixActivate <token> (for VMware backup proxy version 7.0.0 or earlier)
- EnterpriseWorkloadsAgent vmware activate -t <token> (for VMware backup proxy version 7.0.0 and later)

Configuring custom NTP server for CentOS proxy

You can configure Druva VMware backup proxy to use custom NTP server. The NTP requests are serviced through a pool of NTP servers. Currently, the backup proxy uses the

*.centos.pool.ntp.org pool

Open the /etc/ntp.conf file to configure your NTP server.
The NTP server configuration file contains NTP server entries in the following format:

server <ntp_server_fqdn> [options]

For example:

server 0.centos.pool.ntp.org iburst
        server 1.centos.pool.ntp.org iburst
        server 2.centos.pool.ntp.org iburst
        server 3.centos.pool.ntp.org iburst

Comment the existing NTP server entries and add the following entry to the /etc/ntp.conf file.
```
server <internal_ntp_server_fqdn> iburst
```
Restart the ntpd service using the following command:
```
service ntpd restart
```
Verify that the /var/log/messages file now synchronizes with the new NTP server without any errors.

Configuring custom NTP server for Ubuntu proxy

📝 Note
For Ubuntu, the proxy time is synchronized to ntp.ubuntu.com, by default. For more information on the same, refer to https://ubuntu.com/server/docs/network-ntp.

You can configure the Druva VMware backup proxy to use a custom NTP server. The NTP requests are serviced through a pool of NTP servers.

Check if the NTP server is installed.
service ntp status

If the NTP server is installed, continue with step 2. Otherwise, run the following command to install the NTP.
sudo apt install ntp
Open the NTP configuration file
The NTP configuration file is located at /etc/ntp.conf. To edit this file, use a text editor such as vi, nano, or vim.
sudo vi /etc/ntp.conf
Understand the NTP server entries. In the /etc/ntp.conf file, the NTP servers are defined using the server directive. The format is as follows:

server <ntp_server_fqdn> [options]
- <ntp_server_fqdn>: This is the Fully Qualified Domain Name (FQDN) or the IP address of the NTP server.
- [options]: These are optional parameters that modify the behavior of the NTP request. Common options include:
  - iburst: Sends a burst of packets if the server is unreachable, which helps to quickly synchronize the time.
The following is an example of an existing NTP server entry:

server 0.centos.pool.ntp.org

server 1.centos.pool.ntp.org

server 2.centos.pool.ntp.org
Comment out the existing entries. To comment out the existing the NTP server entries, place a # at the beginning of each line:

# server 0.centos.pool.ntp.org

# server 1.centos.pool.ntp.org

# server 2.centos.pool.ntp.org
Add your internal NTP server. For example, if your internal NTP server's FQDN is ntp.company.local, your configuration will be:
server ntp.company.local iburst
Restart the NTP service. After editing the configuration file, you need to restart the NTP daemon (ntpd) to apply the changes:
sudo service ntp restart
Alternatively, on systems using systemd, use the following command:
sudo systemctl restart ntp
Verify the synchronization. To ensure that your system is synchronizing time correctly with the new the NTP server, check the system logs. You can use the following command to view the log file:
sudo tail -f /var/log/dmesg
Check for entries that indicate successful synchronization with the NTP server. For example:
ntpd[1234]: synchronized to 192.168.1.100, stratum 2
This indicates that the NTP daemon is now syncing time with the internal server at 192.168.1.100.
