Recently, we moved to CommVault for backing up VMs. We use a CommVault solution that interacts with NetApp for taking snaps. Once the backup runs, it time-stamps the VM with the last backup taken. If you don’t need an e-mail in HTML format with the report, remove the lines from 103 to 113. Finally, remove the comment line # from line 57 if you want the report on the screen.
Based on this info, I made a script that loops through all clusters and VMs and dumps the report in a mail. You can remove lines 5 to 14 if you don’t want the script scheduled.
# PowerCLI script that lists all VMs under clusters that start with USCORPROD*
# and prints the Last Backup attribute from CommVault
# If the difference between the run time of the script and the last backup is
# more than $HoursDifference, write the output with red color
