Removing Snapshots older than X days

The script below queries virtualcenter for all snapshots and then checks if each one is older than the amount of days you specify in the command line.

If they are older you get a confirmation as to whether to remove or not. Then it moves on to the next snapshot or ends if the last one.

# Usage:
# At the Powershell commandline type ./snapremdate.ps1 30
# This will run the script from your current location attach to your vc
# And query the snapshots, if older than 30 days (or whatever you put above)
# It will ask for confirmation of removal by default but just remove the -Confirm switch
# when happy with it.
