Hi folks, here’s a standard feature of VMware that a lot of people take for granted that I thought would bear mentioning. Snapshots!
So you have an application or patch you want to install and you don’t know what effect it will have on your server. What do you do? Take a snapshot! With VMware you have the ability to take a snapshot of your OS at that point in time and then make whatever changes you desire. After your changes are made you can check to see if everything is working. If there are issues you can just select the snapshot and revert back to where you were before.
I find it quite surprising how many people actually have VMware and forget to use this feature as if they’ve forgotten it’s even existed! Snapshotting can be your best friend when doing upgrades, don’t forget it!
