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.
Cleanedup 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: https://portal.nutanix.com/page/documents/details?targetId=PS-Cmdlets-AOS-v6_5:ps-ps-cmdlets-installation-v2.html
