Each Druva release comes with new features and enhancements, and to use these features, you must have the latest version of Hybrid Workloads agent or backup proxy. Druva regularly provides updates to Druva backup proxy to enable it with new features and enhancements. Updates also include bug fixes and performance improvements.

This section also provides options on how to upgrade Druva backup proxy in your environment. As an administrator, you can upgrade Druva backup proxy using the following methods,

  • Upgrade backup proxy through Management Console
  • Upgrade CentOS backup proxy through RPM
  • Upgrade Ubuntu backup proxy through Debian 

Upgrade backup proxy through Management Console

With the automatic agent upgrade feature, you can upgrade backup proxy to the latest versions from the Management Console with a single click. 

Considerations

Consider the following aspects before you upgrade the backup proxies:

  • Automatic rollback for RPM upgrade is supported from version 4.7.1 and later. 
  • To upgrade the backup proxy from an older version to version 4.7.1 or later, you must deploy the backup proxy. Automatic upgrade is supported from backup proxy version 4.7.1 onwards.
  • If an upgrade is triggered and schedule backup and restore jobs are in queue, the jobs resume after the upgrade is complete.

Procedure

  1. Log in to the Management Console. 
  2. From the top menu bar, select your organization if organizations are enabled. 
  3. Click Protect > VMware. 
    The All Virtual Machines page appears that lists all the registered vCenter/hypervisors. 
  4. You can either select the registered vCenter/ESXi host from the card view or list view or select it from the vCenter/ESXi host list in the left navigation pane.
  5. In the left pane, click Backup Proxies. 
  6. Under the Version column, you can see the current status for each proxy.

Upgrade backup proxy through RPM

 Use the RPM package to upgrade the backup proxy (with CentOS OS).

Before you begin

Ensure that your existing backup proxy can be upgraded using RPM. If you are upgrading from an older backup proxy version to the latest backup proxy version, RPM upgrade can fail. For example, if you try to upgrade backup proxy using RPM, and in the logs you see a message like:

Vddk 6.0.3 not found on backup proxy. To install rpm please deploy latest backup proxy OVA

If you see a message similar to the one above, you cannot upgrade the backup proxy using RPM. To upgrade backup proxy, deploy the latest  backup proxy appliance and reconfigure the virtual machines to use the newly deployed backup proxy. 

If you can upgrade the backup proxy using RPM, download the latest backup proxy and perform the following steps. 

Procedure

From the directory that contains the downloaded RPM, run the following commands:

  1. Open the command prompt.
  2. Run the following command to find the old package name of the Druva installer: 
rpm -qa | grep druva
  1. Run the following command to uninstall the old package:
rpm -e <old_package_name>

When you are prompted Do you want to cleanup all Phoenix config and data files: [yes/no]? [default: no], enter no. 

If you enter yes, all the Hybrid Workloads agent configuration files will be deleted. When you reinstall the agent you will have to reactivate it. 

  1. Run the following command to install the new package, and start the Phoenix service.
      
    rpm –ivh <new_package_name>

    where <new_package name> represents the file name (along with the extension) of the new installer.

  2. Set the vCenter credentials on proxy using the following command: 
    vCenterDetail set <hostfqdn> <username> <password> 
  3. Restart the Phoenix service.

 

Upgrade backup proxy through Debian

Use the Debian package to upgrade the backup proxy (with Ubuntu OS)

To upgrade backup proxy, deploy the latest backup proxy appliance and reconfigure the virtual machines to use the newly deployed backup proxy. 

If you can upgrade the backup proxy using Debian, download the latest backup proxy and perform the following steps.

  1. Open the command prompt.
  2. Run the following command to check currently installed deb package: 
    dpkg -l | grep druva
  3. Run the following command to uninstall current deb package: 
    dpkg -r druva-phoenix-vmware-client
  4. Run the following command to install a deb package: 
    dpkg -i <package name>

Commands to upgrade packages in Ubuntu proxy

To check and install the latest updates, you must run the following commands. These commands fix the security vulnerabilities of application packages and kernel by updating them.

Check pending updates

Run the following command:

apt update && apt list --upgradable

Here, apt-update refreshes the list of available package updates.

Install updates

Run the following command:

apt-get upgrade -y

Here, apt-get upgrade installs the available package updates without upgrading the kernel. If a vulnerability is not patched by Ubuntu in the kernel version present in the proxy, then you must deploy a new OVA.

List Ubuntu repository 

Run the following command to list Ubuntu repositories. This must be allowed if internet access is restricted on proxy infra.

grep -rhE ^deb /etc/apt/sources.list*
