backup client run?

A.
Proxy server

B.
Hypervisor

C.
Virtual machine

D.
Backup device

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.
