Hyper-V Checkpoint

Hyper-V's point-in-time VM capture; production checkpoints use VSS for application-consistent images, while standard checkpoints include memory state.

Definition

Production checkpoints are the default and do not save memory, so the VM boots fresh when applied. Checkpoints create differencing disks (.avhdx) that are merged when deleted.

Example

A production checkpoint is taken before installing a SQL Server update.

Exam tip

Production checkpoints are application-consistent via VSS; they are still not backups.
