1. A method for determining a per-proxy limit of concurrent data streams allowed for backup operations in a storage management system, the method comprising:

  • designating, by a storage manager component of the storage management system, a first data agent to act as coordinator of a first backup job,wherein the first backup job is configured to perform secondary copy operations for a first set of virtual machines in the storage management system,wherein the coordinator data agent executes on a first virtual machine, and wherein the first virtual machine is designated a first proxy, andwherein the first virtual machine executes on a first computing device having one or more processors and non-transitory computer-readable memory;

    designating, by the storage manager, a second data agent to act as controller in the first backup job,wherein the controller data agent executes on a second computing device having one or more processors and non-transitory computer-readable memory, and wherein the second computing device is designated a second proxy; and

    determining, by the coordinator data agent, a respective maximum limit of concurrent data streams assignable by the coordinator data agent to each of the first proxy and the second proxy for performing one or more backup jobs in the storage management system, including the first backup job,wherein for a given proxy the respective maximum limit of concurrent data streams is based on a processing capacity and an amount of random-access memory of the given proxy.
