<title>Snapshots</title>

<p>
With snapshots, you can save a particular state of a virtual
machine for later use. At any later time, you can revert to that
state, even though you may have changed the VM considerably since
then. A snapshot of a virtual machine is thus similar to a machine
in Saved state, but there can be many of them, and these saved
states are preserved.
</p>
<p>
To see the snapshots of a virtual machine, click on the machine
name in VirtualBox Manager. In the machine tools menu for the VM, click
<b outputclass="bold">Snapshots</b>. The Snapshots tool is
displayed.
</p>
<fig id="fig-snapshots-tool">
<title>Snapshots Tool, Showing Snapshot Properties</title>
<image href="images/snapshots-1.png" width="10cm" placement="break"/>
</fig>
<p>
If you select multiple VMs in the machine list, all snapshots are
listed for each VM.
</p>
<p>
Until you take a snapshot of the virtual machine, the list of
snapshots will be empty, except for the
<b outputclass="bold">Current State</b> item. This item
represents the current point in the lifetime of the virtual
machine.
</p>
<p>
The Snapshots window includes a toolbar, enabling you to perform
the following snapshot operations:
</p>
<ul>
<li>
<p>
<b outputclass="bold">Take.</b> Takes a snapshot of the
selected VM. See
<xref href="snapshots-take-restore-delete.dita#snapshots-take-restore-delete"/>.
</p>
</li>
<li>
<p>
<b outputclass="bold">Delete.</b> Removes a snapshot
from the list of snapshots. See
<xref href="snapshots-take-restore-delete.dita#snapshots-take-restore-delete"/>.
</p>
</li>
<li>
<p>
<b outputclass="bold">Restore.</b> Restores the VM
state to be the same as the selected snapshot. See
<xref href="snapshots-take-restore-delete.dita#snapshots-take-restore-delete"/>.
</p>
</li>
<li>
<p>
<b outputclass="bold">Properties.</b> Displays the
properties for the selected snapshot. The
<b outputclass="bold">Attributes</b> tab is used to
specify a Name and Description for the snapshot. The
<b outputclass="bold">Information</b> tab shows VM
settings for the snapshot.
</p>
</li>
<li>
<p>
<b outputclass="bold">Clone.</b> Displays the
<b outputclass="bold">Clone Virtual Machine</b> wizard.
This enables you to create a clone of the VM, based on the
selected snapshot.
</p>
</li>
<li>
<p>
<b outputclass="bold">Settings.</b> Available for the
Current State snapshot only. Displays the
<b outputclass="bold">Settings</b> window for the VM,
enabling you to make configuration changes.
</p>
</li>
<li>
<p>
<b outputclass="bold">Discard.</b> For a running VM,
discards the saved state for the VM and closes it down.
</p>
</li>
<li>
<p>
<b outputclass="bold">Start.</b> Start the VM. This
operation is available for the <b outputclass="bold">Current
State</b> item.
</p>
</li>
</ul>
