VM snapshots: Snapshots (or checkpoints for Hyper-V) record the state of a VM at a point in time, including all data, memory, devices on the network, network interfaces, and power state. Virtual Machine Backup vs Snapshot, Are They the Same?Ī common myth about VM backup is how it differs from the VM snapshot and whether they can replace each other? To answer this, let's take a closer look at the 2 concepts: Implementing a good VM backup strategy can enable faster disaster recovery, and keep business continuity. Therefore, it is essential to create virtual machine backup regularly.īy creating VM backups, you can effectively ensure that important data can be restored in time if it is lost. Whichever host you are running VMs on, there may be data loss caused by virtual server or physical device failures, abnormal shutdown, or other mis-operations. VMware Workstation is the most commonly used type 2 hypervisor. Type 2 hypervisor: also known as hosted hypervisor, runs on top of the operating system of the host machine. VMware ESXi and Microsoft Hyper-V are the most commonly used type 1 hypervisor. Type 1 hypervisor: also known as bare-metal hypervisor, runs directly on the computing hardware. Virtual machines are run on hypervisor, and a hypervisor allows one host computer to support multiple guest VMs by virtually sharing its resources. It allow users to run an operating system in a single application window, providing a secure sandbox to test programs or access virus-infected data.
