The system determines threshold parameters for each respective virtual proxy in a plurality of virtual proxies. The system receives virtual machine protection data of each respective virtual proxy. The system detects a current data protection workload experienced by each virtual proxy operating according to its respective threshold parameters and virtual machine protection data. The system identifies at least one under-utilized virtual proxy and at least one over-utilized virtual proxy based on the current data protection workload detected on each virtual proxy. The system causes the at least one under-utilized virtual proxy to receive upcoming backup data flow before the at least one over-utilized virtual proxy. ## Claims ### Claim 1 A system comprising: one or more processors;
