Best Practices for Virtual Machine Snapshots
What is a virtual machine snapshot and how does it work?
Virtual machine snapshots are a powerful tool in virtualization environments. They capture the state of a virtual machine at a specific point in time, allowing you to revert back to that snapshot if needed. However, not all aspects of a virtual machine are captured in a snapshot. Which one of the items below does NOT get captured in a snapshot?
Answer:
The item that does NOT get captured in a virtual machine snapshot is Independent virtual disks.
Virtual machine snapshots are essential for data protection and disaster recovery in virtualized environments. They provide a way to capture the current state of a virtual machine, including its virtual disks, virtual CPUs, and virtual memory.
However, when it comes to Independent virtual disks, the snapshot would only capture the state of the virtual disks themselves. Independent virtual disks are designed to be self-contained and do not rely on other virtual machines or components to function. As a result, the state of the virtual machines or virtual CPUs is not captured in a snapshot of Independent virtual disks.
On the other hand, snapshots of VM configuration and VM memory state do capture the full state of the virtual machines, including virtual disks, virtual CPUs, and virtual memory. These snapshots are useful for restoring the virtual machines to a previous state if needed or monitoring their performance and resource usage.
In conclusion, it is important to understand what aspects of a virtual machine snapshot capture and how they work to ensure effective data protection and recovery strategies in virtualized environments.
