FAQs

What is VM snapshots?

Virtual machine snapshots basically help to preserve the data and state of a virtual machine at some point in time. You can also consider that a VM snapshot is a copy of the disk file of your Virtual machine. VM snapshots are very helpful to immediately recover a virtual machine from a disaster.

Consider there is a scenario where you want to get certain data from the snapshot without restoring the complete VM. In that case, one of the excellent ways is to create a VM from the snapshot and get the specific data that you need.
