Explanation

Image-based Backup Image-based backup operates at the hypervisor level and essentially takes a snapshot of the VM. It creates a copy of the guest OS and all the data associated with it (snapshot of VM disk files), including the VM state and application configurations. The backup is saved as a single file called an "image" and this image is mounted on the proxy server (acts as a backup client). The backup software then backs up these image files normally. This effectively offloads the backup processing from the hypervisor and transfers the load on the proxy server, thereby reducing the impact to VMs running on the hypervisor. Image-based backup enables quick restoration of a VM.
