I have installed Veeam trial version to backup virtual servers on VMware host. However, I came across with a backup job failure because of compatibility problem with Veeam and VMWare. After searching it on google, I implemented a solution.
Upgrade Veeam backup as shown below. Go to official website and download whole installation iso file, not to download upgrade pack which does not work.
I downloaded Veeam backup and run it to upgrade my older version. Not to install it again.
Finally, a successful job was completed, shown below.
