which just pile up as the days go on. I think this is some sort of bug in either vSphere API or the way NetApp handles snapshotting during the backup window.

Before executing the script you will need to run the following to save vCenter hostname, username and password in a credentials file:

For email alert section to work you need to modify $emailFrom and $emailTo variables.

All that’s left is to schedule the script to run on a daily basis and never have this problem again!

Example email you should get in your inbox once the script has done its job:
