VM Snapshots and Restore Points for Enterprise Hosts
Overview of VM Snapshots
VM snapshots are a feature of vSphere Hypervisor that allows users to capture the state of a VM at a particular point in time. Snapshots can be used to:
- Roll back to a previous state in case of errors or issues
- Test new software or configurations without affecting the production environment
- Clone VMs for development or testing purposes
Creating and Managing Snapshots
Creating and managing snapshots in vSphere Hypervisor is a straightforward process:
- Log in to the vSphere Web Client and select the VM you want to snapshot.
- Click on the
