Understanding Hyper-V Checkpoints on Windows Server 2016
1. What are the two types of checkpoints supported by Hyper-V running on Windows Server 2016 host?
The two types of checkpoints supported by Hyper-V running on Windows Server 2016 host are Standard Checkpoints and Production Checkpoints.
Standard Checkpoints
Standard Checkpoints capture: the state, data, and hardware configuration of the running VM. They provide a quick and easy way to restore a VM to its previous state or troubleshoot it.Production Checkpoints
Production Checkpoints use backup technology: inside the VM to create a VM checkpoint. They save memory state, configuration files, application data, and other information, including the state of all virtual machine disks. They are primarily intended for VMs running a supported OS and are used for application-aware backup and restore scenarios.2. True or False. You can edit the first virtual hard disk of a guest virtual machine with checkpoint or snapshot enabled.
False. Once a virtual machine has a checkpoint or snapshot enabled, the first virtual hard disk of a guest virtual machine is write-protected.
When a checkpoint or snapshot is taken, Hyper-V creates a differencing disk that stores all write operations on the VM’s disk during that time. The differencing disk is chained to the parent virtual hard disk, making it read-only to maintain the state at the time the snapshot was taken.
