The illustrative systems and methods consolidate storage-array command channels into a media agent that executes outside the production environment. A “snapshot-control media agent” (“snap-MA”) is configured on a secondary storage computing device that operates apart from client computing devices. A “forwarder” media agent operates on each client computing device that uses the storage array, yet lacks command channels to the storage array. Likewise, a “forwarder” proxy media agent may operate without command channels to the storage array. No third-party libraries or storage-array-command devices are installed or needed on the host computing device. The forwarder media agent forwards any commands directed at the storage array to the snap-MA on the secondary storage computing device. The snap-MA receives and processes commands directed at the storage array that were forwarded by the forwarder media agents. Responses from the storage array are transmitted to the respective forwarder media agent. The snap-MA advantageously pools any number of storage-array-command devices so that capacity limitations in regard to communications channels at the storage array may be avoided. As a result, the snap-MA operating in conjunction with the forwarder media agents enable the illustrative system to consolidate the communication of storage-array commands away from client computing devices and/or proxy media agent hosts and into the secondary storage computing device that hosts the snap-MA.
1. A method comprising: receiving, by a first media agent executing on a client computing device, a command that requests a storage array to perform a snapshot-related operation within the storage array, wherein the storage array stores primary data that is directly accessible for read and write ope
1. A method comprising: receiving, by a first media agent executing on a client computing device, a command that requests a storage array to perform a snapshot-related operation within the storage array, wherein the storage array stores primary data that is directly accessible for read and write operations by one or more applications that execute on the client computing device, andwherein the command is received by the first media agent from at least one of a storage manager and a data agent associated with at least one of the one or more applications;forwarding the command by the first media agent to a snapshot-control media agent that executes on a secondary storage computing device, wherein the first media agent on the client computing device is configured without a command device for communicating the command to the storage array, andwherein the snapshot-control media agent on the secondary storage computing device is configured with a command device for communicating the command forwarded by the first media agent to the storage array;executing, by the storage array, the requested snapshot-related operation in response to the command received via the command device configured on the snapshot-control media agent;receiving, by the first media agent from the snapshot-control media agent, a status from the storage array based on the snapshot-related operation within the storage array; andwherein by being configured without a command device and by forwarding the command to the snapshot-control media agent, the first media agent protects the client computing device from communicating the command to the storage array. 2. The method of claim 1 wherein the command directed at the storage array and received by the first media agent requests the storage array to take and store a snapshot of a volume on the storage array. 3. The method of claim 1 wherein the command that is directed at the storage array and received by the first media agent does not comprise primary data stored by the storage array. 4. The method of claim 1 wherein the command directed at the storage array is issued to the first media agent by a storage manager before being forwarded by the first media agent to the snapshot-control media agent. 5. The method of claim 1 wherein the command directed at the storage array is issued to the first media agent by a data agent on the client computing device before being forwarded by the first media agent to the snapshot-control media agent. 6. The method of claim 1 wherein the command directed at the storage array is received by the first media agent from at least one of the storage manager, which executes on another computing device distinct from the client computing device, and the data agent, which also executes on the client computing device. 7. A method for forwarding commands directed at a storage array from a first secondary storage computing device to a second secondary storage computing device, using a snapshot-control media agent, the method comprising: receiving, by a proxy media agent executing on the first secondary storage computing device, a command that requests a storage array to perform a snapshot-related operation within the storage array, wherein the storage array stores primary data that is directly accessible for read and write operations by one or more applications that execute on a client computing device in communication with the first secondary storage computing device, andwherein the command is received by the proxy media agent from at least one of a storage manager and a data agent associated with at least one of the one or more applications;forwarding the command, by the proxy media agent to the snapshot-control media agent which executes on the second secondary storage computing device, wherein the proxy media agent on the first secondary storage computing device is configured without a command device for communicating the command to the storage array, andwherein the snapshot-control media agent on the second secondary storage computing device is configured with a command device for the snapshot-control media agent to communicate to the storage array the command forwarded by the proxy media agent;executing, by the storage array, the requested snapshot-related operation in response to the command received from the snapshot-control media agent;receiving, by the proxy media agent from the snapshot-control media agent, a status from the storage array based on the snapshot-related operation within the storage array; andwherein by being configured without a command device and by forwarding the command to the snapshot-control media agent, the proxy media agent protects the first secondary storage computing device from communicating the command to the storage array. 8. The method of claim 7 wherein the command received by the proxy media agent and directed at the storage array requests the storage array to take and store a snapshot of a volume on the storage array. 9. The method of claim 7 wherein the command directed at the storage array is issued to the proxy media agent by a storage manager. 10. The method of claim 7 wherein the command directed at the storage array is issued to the proxy media agent by a data agent. 11. The method of claim 7 wherein the command directed at the storage array is received by the proxy media agent from at least one of a storage manager and a data agent. 12. A system for forwarding commands directed at a storage array from a client computing device to a secondary storage computing device, based on a media agent at the client computing device, the system comprising: the client computing device comprising one or more executable applications and a first media agent for accessing data stored on the storage array, wherein the client computing device is a physical computing device that comprises one or more processors and corresponding computer memory, andwherein the first media agent on the client computing device is configured with no command device for communicating commands to the storage array;the storage array, comprising primary data that is directly accessible for read and write operations by the one or more applications that execute on the client computing device;wherein the first media agent is executable on the client computing device and is configured to: receive a command that requests the storage array to perform a snapshot-related operation within the storage array, wherein the command is received from at least one of a storage manager and a data agent associated with at least one of the one or more applications,forward the command to a snapshot-control media agent on the secondary storage computing device that is distinct from the client computing device, wherein the snapshot-control media agent is executable on the secondary storage computing device,wherein the snapshot-control media agent is configured with a command device for communicating the command to the storage array;receive from the snapshot-control media agent, a status from the storage array based on the snapshot-related operation within the storage array executed in response to the command; andwherein the system is configured to forward commands directed at the storage array from the receiving first media agent and away from the client computing device and into the secondary storage computing device for communication to the storage array thereby. 13. The system of claim 12 wherein the first media agent is configured to prevent the client computing device from establishing a direct command channel to the storage array via a command device. 14. The system of claim 12 wherein the first media agent comprises a forwarder module that determines whether to communicate the command to the storage array, and if direct communications with the storage array are not possible, the forwarder module is configured to forward the command to the snapshot-control media agent.
