Abstract

A system according to certain aspects improves the process of performing data protection operations (e.g., creating backup copies in a secondary storage device). The system can generate network path information based on client information associated with client computing devices (e.g., application type, data type, client device ID, etc.) and process requests to perform data protection operations based on the network path information specified in the requests. For example, the system may use the specified network path information to determine the data types of the primary data stored on the client computing devices and store backup copies of the primary data at the location indicated by the network path information.

Claims

1. A method for performing a backup operation in a data storage system, the method comprising:

with a media agent comprising one or more hardware processors and in communication with one or more secondary storage devices,

receiving, from a storage manager, a first request to generate network path information associated with a client computing device, the first request including client information identifying at least a data type of primary data stored on one or more primary storage devices associated with the client computing device;

generating the network path information based on the client information, the network path information identifying a location within the one or more secondary storage devices that is associated with the client computing device;

transmitting the generated network path information to the storage manager;

receiving, from the client computing device, a second request to store a copy of the primary data stored on the one or more primary storage devices onto the one or more secondary storage devices associated with the media agent as part of a data protection operation, the second request including the network path information generated by the media agent; and

causing, based on the network path information, the copy of the primary data to be stored in the location within the one or more secondary storage devices associated with the client computing device.

2. The method of claim 1, further comprising identifying the data type of the primary data stored on the one or more primary storage devices based on the network path information.

3. The method of claim 1, further comprising causing the network path information to be stored in association with an identity of the client computing device in a mapping table.

4. The method of claim 1, wherein the network path information is a unique string that identifies a network directory accessible by the client computing device according to a network file system (NFS) protocol.

5. The method of claim 1, wherein the second request is a mount request requesting access to a network directory according to a network file system (NFS) protocol.

6. The method of claim 1, wherein the media agent is physically separate from the client computing device.

7. The method of claim 1, further comprising transmitting address information associated with a network file system (NFS) server to the storage manager.

8. The method of claim 1, wherein the client information further includes an identity of the client computing device.

9. A system for performing a backup operation in a data storage system, the system comprising:

one or more secondary storage devices comprising computer hardware and configured to store backup copies of client data associated with a client computing device; and

a first computing device comprising one or more hardware processors and in communication with the one or more secondary storage devices, wherein the first computing device is configured to;

receive, from a second computing device, a first request to generate network path information associated with the client computing device, the first request including client information identifying at least a data type of primary data stored on one or more primary storage devices associated with the client computing device;

generate the network path information based on the client information, the network path information identifying a location within the one or more secondary storage devices that is associated with the client computing device;

transmit the generated network path information to the second computing device;

receive, from the client computing device, a second request to store a copy of the primary data stored on the one or more primary storage devices onto the one or more secondary storage devices associated with the first computing device as part of a data protection operation, the second request including the network path information generated by the first computing device; and

cause, based on the network path information, the copy of the primary data to be stored in the location within the one or more secondary storage devices associated with the client computing device.

10. The system of claim 9, wherein the first computing device is further configured to identify the data type of the primary data stored on the one or more primary storage devices based on the network path information.

11. The system of claim 9, wherein the first computing device is further configured to cause the network path information to be stored in association with an identity of the client computing device in a mapping table.

12. The system of claim 9, wherein the second request is a mount request requesting access to a network directory according to a network file system (NFS) protocol.

13. The system of claim 9, wherein the network path information is a unique string that identifies a network directory accessible by the client computing device according to a network file system (NFS) protocol.

14. The system of claim 9, wherein the first computing device is physically separate from the client computing device.

15. Non-transitory physical computer storage comprising executable instructions stored thereon that, when executed by one or more processors, configure the one or more processors of a first computing device to implement operations for performing a backup operation in a data storage system, the operations comprising:

receiving, from a second computing device, a first request to generate network path information associated with a client computing device, the first request including client information identifying at least a data type of primary data stored on one or more primary storage devices associated with the client computing device;

generating the network path information based on the client information, the network path information identifying a location within the one or more secondary storage devices that is associated with the client computing device;

transmitting the generated network path information to the second computing device;

receiving, from the client computing device, a second request to store a copy of the primary data stored on the one or more primary storage devices onto the one or more secondary storage devices associated with the first computing device as part of a data protection operation, the second request including the network path information generated by the first computing device; and

causing, based on the network path information, the copy of the primary data to be stored in the location within the one or more secondary storage devices associated with the client computing device.

16. The non-transitory physical computer storage of claim 15, wherein the operations further comprise identifying the data type of the primary data stored on the one or more primary storage devices based on the network path information.

17. The non-transitory physical computer storage of claim 15, wherein the operations further comprise causing the network path information to be stored in association with an identity of the client computing device in a mapping table.

18. The non-transitory physical computer storage of claim 15, wherein the network path information is a unique string that identifies a network directory accessible by the client computing device according to a network file system (NFS) protocol.

19. The non-transitory physical computer storage of claim 15, wherein the second request is a mount request requesting access to a network directory according to a network file system (NFS) protocol.

20. The non-transitory physical computer storage of claim 15, wherein the first computing device is physically separate from the client computing device.
