What other important considerations should I be aware of when using snapshots?

Keep the following considerations in mind, especially if you plan to use snapshots on a virtual machine in a production environment:

  • The presence of a virtual machine snapshot reduces the disk performance of the virtual machine.
  • When you delete a snapshot, the .avhd files that store the snapshot data remain in the storage location until the virtual machine is shut down, turned off, or put into a saved state. As a result, when you delete a snapshot, you will need to put the production virtual machine into one of those states at some point to be able to complete the safe removal of the snapshot.
  • We do not recommend using snapshots on virtual machines that provide time-sensitive services, or when performance or the availability of storage space is critical.
