Save Snapshots of a Virtual Machine
A snapshot is a saved state of the guest OS. It's useful to create snapshots, for example, before:
Note: 1. Snapshots cannot be created for Windows virtual machines that use the Boot Camp partition.
2. If your virtual machine has one or more snapshots, you can neither compress nor resize the virtual hard disk.
If something goes wrong, you can revert the changes back to any of your snapshots and continue working with the guest OS.

Automate the Creation of Snapshots
The SmartGuard functionality allows you to automate snapshots creation.
Note: SmartGuard is available only when the Undo Disks feature is disabled and the virtual machine is not running in Safe Mode.
To access settings for automating snapshots:
To automate snapshots, click the SmartGuard menu and choose one of the following:
If you want to know when it is time to make the next snapshot and to be able to reject the snapshot creation, enable the Notify me before snapshot creation option.
Note: If you use Time Machine to back up your Mac, you can configure the virtual machine so that Time Machine would back up not its whole hard disk but only the changes made since the latest snapshot. Choose Optimize for Time Machine and click OK.
To set how often snapshots are made:
If the time interval is less than 24 hours, SmartGuard will allow you to restore the latest hourly, daily and weekly snapshot. If the time interval is more than 24 hours, you will be able to restore the latest daily, weekly and monthly snapshot.
To limit how many snapshots are stored:
The maximum available value is 100 snapshots. As soon as Snapshots Manager reaches the limit for snapshots and needs to make a new one over limit, it deletes the oldest snapshot.

To delete a snapshot:
When you delete an intermediate snapshot, the information it contains is merged into the next snapshot.
