The snapshot feature is available on every virtualization platform—whether you use Proxmox, Hyper-V, VMware or other virtualization tool. A snapshot enables you to preserve the state of a virtual machine, including virtual memory, virtual disks, and settings. Proxmox VE allows you to create live snapshots of the VM so that you can roll back to the point in time when something went wrong.
