Cleanup Nutanix Snapshots After # Amount Of Days

Quick blog post. The PowerShell script is self explaining 😉

    This script checks the Nutanix cluster for available snapshots (Protection Domain snapshots are not part of the check).
    The list of snapshots is checked against the $DeleteAfterDays and is the snapshot is older then the given days it will be deleted.
    Cleaned up space is freed after curator has done his magics ;)
    Please change $DeleteAfterdays, $DryRun, $PrismElementIP, $UserName, $Password to match your needs.
    The $DryRun can be $True or $False. When it is $True no real snapshots will be deleted.
    Remove the "-password" in the connect string and the script will ask for you password. ;)
    Make sure the powershell cmdlets are installed. More info here:
