A snapshot is a temporary copy of the data in a virtual machine
(copy virtual disks). This creates a restore point that allows
returning a virtual machine to a previous status.
A Snapshot can be very useful if you do an upgrade or major
alteration of the operating system or applications in a virtual
machine. If something goes wrong, we can return to the status when
the machine was, at the time the snapshot was taken.
When the snapshot is no longer needed, it is recommended to delete
as soon as possible, because its existence generates a degradation
in the performance of the virtual machine.
When the virtual machine is turned off, access the menu Virtual
Machines, select the desired virtual machine and click on the
Virtual Machine Snapshot button.
Click on the button Take snapshot now.
The snapshot creation process starts.
When the process is completed the snapshot are listed.
To restore a snapshot, click on the Restore button. In the
question "DANGER: THIS WILL OVERWRITE YOUR CURRENT VM DISKS WITH THE
SNAPSHOT CONTENTS. Do you really want to continue?". If you are sure
to click OK. The system immediately restores the selected
snapshot.
This may take a while, depending on the size of the disks. Once we
completed we can start the virtual machine.
