Locate the Management section on the left side of the dialog and select the Checkpoints entry.

Right-click the name of the desired VM and select Settings.

The basic steps to enable or disable checkpoints are:

Administrators can also use Hyper-V Manager to change checkpoint types, use automatic checkpoints, or change checkpoint file locations. Hyper-V administrators can manually enable or disable checkpoints as desired using Hyper-V Manager. Production checkpoints are enabled by default in Hyper-V, and admins can change them to standard or back using Hyper-V Manager or PowerShell. Standard checkpoints are most commonly used in development environments, or when admins use previous VM states to test and troubleshoot problems.Ī production checkpoint uses backup technologies or tools, such as Volume Shadow Copy Service, to create a data-consistent VM image that admins can restore later and continue normal operation with no loss of data. Such restoration problems are common for transacting sensitive VM workloads such as Exchange and SQL. When the checkpoint is restored, some data or transactions may be lost. The difference is in data consistency.Ī standard checkpoint only provides application consistency, not data consistency. Both capture the state, data and configuration details of a running VM. There are two types of checkpoints in Hyper-V: standard checkpoints and production checkpoints. Thus, every checkpoint works together to create a sequence of state changes called a 'checkpoint tree.' How Hyper-V checkpoints work The first checkpoint represents the entire VM, but subsequent checkpoints would contain only the changes between the current state and the previous checkpoint. The differencing file represents the difference between the VM's current state and VM's state at its last checkpoint. This undoes or discards any changes that the troubled process introduced and should return the VM to its working state. If the process results in problems - such as installation failures, undetected bugs or other compatibility or performance issues - the IT administrator can revert, restore or rollback the VM to its previous known-good state. Once a known-good state is established, the upgrade can proceed as planned. Admins typically capture a checkpoint before performing a major process such as patching or upgrading the software within the VM.
