Remove Snapshots script

One approach to selectively delete snapshots in a vCenter, specifically targeting those created by specific individuals, involves utilizing a ‘TAG’ system applied to either the snapshot name or description. This method allows for the identification and subsequent deletion of snapshots based on the specified criteria, rather than removing all snapshots across the vCenter environment.

Usage:

.\remove-snapshots.ps1 -vcenter vcsa.local -username * -password * -tag “autodelete”
