I’ve come up with this Windows PowerShell script to help identify virtual machines that have snapshots older than 1 day. It generates a CSV file and emails specified recipients. This is particularly handy in large VMware environments where snapshots can cause major havoc on datastore utilization. Enjoy!

Just over a year. That is far too long to let this site sit and go to waste. I’m in the process of cooking up some articles so look forward to them as I’ve learned a lot in the past year. I’ve moved all of my projects to erickiel.com so go check them out. I’m also working on an update to the OpenNote theme – look forward to better code handling as well as a darker theme that is easier on the eyes and inspired by Crunchbang. See you soon!
