When developing a lab, you may find you want or need to restore or rollback the Virtual Machines to a previous point to do something a different a way. This is where you would use Snapshots, which are temporary restore points available during that session of the lab.
You have to enable snapshots before launching the lab in order to use them within the lab. To do this:
Select Edit on the Lab Profile page.
Select the Advanced tab.
In the Maximum Allowed Snapshots field, type the number of snapshots you want available.
Select Save and launch the lab.
Once the lab is running and you are working on it, you can create a snapshot at any time.
To create a snapshot:
Select the Commands menu at the top of the lab interface
Select Snapshots. In the Snapshots window
Type the name of the snapshot and select Create Snapshot. This creates a snapshot of all machines in the lab.
To restore to a snapshot:
Open the Snapshots window again and select Apply next to the snapshot you want to restore the machines to.
Select OK to confirm the action.
