If the snapshot includes the memory state, the virtual machine will be in the same power state as when
you created the snapshot.
Table 3‑4. Virtual Machine Power State After Restoring a Snapshot
Virtual Machine State When Parent Snapshot Is
Taken Virtual Machine State After Restoration
Powered on (includes memory) Reverts to the parent snapshot, and the virtual machine is
powered on and running.
Powered on (does not include memory) Reverts to the parent snapshot and the virtual machine is
powered o.
Powered o (does not include memory) Reverts to the parent snapshot and the virtual machine is
powered o.
Virtual machines running certain kinds of workloads can take several minutes to resume responsiveness
after reverting from a snapshot.
N vApp metadata for virtual machines in vApps does not follow the snapshot semantics for virtual
machine conguration. vApp properties that are deleted, modied, or dened after a snapshot is taken
remain intact (deleted, modied, or dened) after the virtual machine reverts to that snapshot or any
previous snapshots.
Revert to a Snapshot in the VMware Host Client
Revert to a snapshot to restore the virtual machine to the state of the snapshot.
Prerequisites
Verify that you have the Virtual machine.Snapshot management.Revert to snapshot privilege on the
virtual machine.
Procedure
1 Click Virtual Machines in the VMware Host Client inventory.
2 Right-click the virtual machine in the list, select Snapshots, and select Revert to snapshot from the pop-
up menu.
N The current state of the virtual machine will be lost unless you save it in a snapshot.
3 Click Revert to revert the virtual machine to the most recent snapshot.
Deleting Snapshots
Deleting a snapshot removes the snapshot from the Snapshot Manager. The snapshot les are consolidated
and wrien to the parent snapshot disk and merge with the virtual machine base disk.
Deleting a snapshot does not change the virtual machine or other snapshots. Deleting a snapshot
consolidates the changes between snapshots and previous disk states and writes all the data from the delta
disk that contains the information about the deleted snapshot to the parent disk. When you delete the base
parent snapshot, all changes merge with the base virtual machine disk.
To delete a snapshot, a lot of information needs to be read and wrien to a disk. This can reduce virtual
machine performance until consolidation is complete. Consolidating snapshots removes redundant disks,
which improves virtual machine performance and saves storage space. The time it takes to delete snapshots
and consolidate the snapshot les depends on the amount of data that the guest operating system writes to
the virtual disks after you take the last snapshot. The required time is proportional to the amount of data the
virtual machine is writing during consolidation if the virtual machine is powered on.
