Abstract: Techniques for managing proxy virtual machines are disclosed. In some embodiments, a computer system deploys proxy virtual machines on a data center in an intelligent way in order to optimize performance and efficiency for backing up data from and restoring data to the data center, using the topology of the data center to determine how many proxy virtual machines to deploy and on which specific hosts to deploy the proxy virtual machines. Rather than determining the number of proxy virtual machines to deploy based on a maxing out of all of the ports on each proxy virtual machine to handle a planned quantity of backup jobs, the computer system may calculate the number of proxy virtual machines to use based on a rule that ports be left available for un-planned on-demand restore jobs.
