Intelligent local management of data stream throttling in secondary-copy operations

At least one computer-readable medium, excluding transitory propagating signals, storing instructions that, when executed by a computing device comprising one or more processors and computer memory, perform a method for management of data stream throttling in a storage management system, the method comprising:

• receiving, by a first data agent that executes on the computing device, instructions for a first copy job for first primary data associated with the first data agent,
• wherein the instructions comprise one or more parameters for one or more first data streams that are to be used by the first data agent for transferring the first primary data to a first media agent during the first copy job;
• transmitting, by the first data agent, to a throttling manager, one or more respective registrations for the one or more first data streams,
• wherein the throttling manager also executes on the computing device;
• receiving, by the first data agent, from the throttling manager, respective first bandwidth values for the one or more first data streams;
• executing the first copy job, at least in part by the first data agent,
• wherein the first copy job comprises transferring at least part of the first primary data to the first media agent via the one or more first data streams at the respective first bandwidth values received from the throttling manager, and
• wherein the one or more first data streams originate from the first client computing device;
• receiving, by the first data agent, from the throttling manager, respective second bandwidth values for the one or more first data streams used by the first copy job;
• continuing the one or more first data streams at the respective second bandwidth values received from the throttling manager, wherein the respective second bandwidth values differ from the respective first bandwidth values;
• after the first copy job is completed, transmitting, by the first data agent, to the throttling manager, respective de-registrations for the one or more first data streams;
• and
• wherein the first bandwidth values are changed to the second bandwidth values, based on a second copy job executed at least in part by a second data agent that also executes on the computing device,
• wherein the second copy job utilizes one or more second data streams that are registered with the throttling manager, and
• wherein the one or more second data streams used by the second copy job also originate at the first client computing device and are to be used for transferring second primary data to the first media agent during the second copy job.
