Snapshot a Volume on VM
Snapshots are point-in-time copies of the current state of your volumes. Snapshots allow you a quick and easy way to backup you systems and can be used to return your system to a previous state in cases of failure or corruption.
To detach a volume, from your virtual machine's view, click on the "Volumes" tab, then click on the icon to the far right of the target volume.
Note: You can only snapshot one volume at a time. To make certain you have completely captured your entire VM, make sure you snapshot EVERY volume associated with it.
