VirtualBox is a virtualization tool that allows users to create virtual machines on their computer. One of its most useful features is the ability to take snapshots of a virtual machine at a specific point in time. The snapshots They are like snapshots that capture the state of the virtual machine at a given moment, allowing users to roll back changes or restore the machine to a previous state if something goes wrong. In this article, we will show you how to work with snapshots in VirtualBox so you can get the most out of this feature.

– Step by step -- How to work with snapshots in VirtualBox?

• What are snapshots in VirtualBox? Snapshots are a VirtualBox feature that allows you to save the current state of a virtual machine at a given time. This includes memory status, virtual disk, and machine configuration.
• Why use snapshots?Snapshots are useful for creating backup copies, test new configurations without affecting the major version of the virtual machine, or to revert to a previous state if something goes wrong.
• Create a snapshot it's simple. First, select the virtual machine in the main VirtualBox window. Then, click on the “Machine” option in the menu bar and choose “Take a snapshot.” In the window that appears, enter a descriptive name for the snapshot and optionally add a description.
• Restore or delete a snapshot It's just as simple. Simply select the virtual machine, go to the “Snapshots” tab, right-click on the snapshot you want to restore or delete, and choose the corresponding option.
• Manage multiple snapshots It is possible, since VirtualBox allows you to take several snapshots of the same virtual machine. You can navigate between them, restore any previous snapshots, or delete any you no longer need.
