Dynamically generating proxy virtual machines (VMs) in a virtual center (vCenter) serving a backup server, by deploying a source proxy VM by passing network data to the vCenter, passing a set of internet protocol (IP) addresses and network configuration information to the vCenter to be used by the dynamically generated proxy VMs, receiving an indication from the backup server that new proxy VMs are required, and performing, in the vCenter, an instant clone operation to spawn one or more new proxy VMs. The method may further comprise passing the IP address and network configuration information for the new proxy VMs to the backup server for registration within the backup server, and using the new proxy VMs for backup operations of the backup server.
