A native Hyper-V-based checkpoint creates a snapshot of a VM on the physical host volume or cluster volume.
Note: Native Hyper-V checkpoints (snapshots) are not the same as PowerStore storage snapshots. PowerStore array-based snapshots and native Hyper-V snapshots function independently.
Each extra Hyper-V checkpoint creates another snapshot. They are stored in a hierarchical tree.
Hyper-V snapshots are mentioned here because of their impact on storage read performance. A long chain of Hyper-V checkpoints can degrade read performance. During a read operation, the requested blocks might reside in different checkpoints, which can increase read latency enough to impact performance.
We recommend avoiding using Hyper-V checkpoints, or using them sparingly or temporarily.
Administrators can use PowerStore array-based snapshots to protect and replicate VM data, in addition to using native Hyper-V VM replication tools.
