Ways of Using Snapshots

Always Saving Changes (No Snapshot)

Making Risky Changes
If!you!plan!to!make!risky!changes!in!a!virtual!machine!(for!example,!testing!new!
software!or!examining!a!virus),!take!a!snapshot!before!you!begin!to!make!those!
changes.!If!you!encounter!a!problem,!click!Revert!on!the!console!toolbar!to!return!the!

!time!you!took!the!snapshot.
If!the!first!action!you!take!causes!no!problems!and!you!want!to!protect!the!virtual!
machine!in!its!new!state,!you!can!take!a!new!snapshot.!You!can!have!only!one!snapshot!
