Abstract

The present invention includes a system for simulating the performing of data storage operations. The system may include a storage manager component, at least one media management component directed by the storage manager component to manage storage operations to at least one storage device, and a storage emulation module adapted to simulate the characteristics of the at least one storage device. Under the direction of the storage manager, the emulation module may be adapted to simulate storage operations to one or more storage devices performed by one or more of the media management components.

Claims

1. (canceled)

2. A computing system for simulating data storage operations, the computing system comprising:

at least one virtual data agent executing in one or more computer processors, the virtual data agent configured to obtain application specific data associated with an application, wherein the application specific data comprises a plurality of different data formats, the virtual data agent further comprising a plurality of data agents wherein each data agent is associated with one of the different data formats of the application specific data; and

a storage device emulation module executing in one or more computers, wherein the storage device emulation module comprises different types of simulated storage devices, wherein the different types of simulated storage devices are configured to simulate storage operations associated one or more of the different types of application specific data obtained by the virtual data agent.

3. The virtual machine of claim 2, wherein the different types of simulated storage devices are selected based on the different data formats of the application specific data.

4. The virtual machine of claim 2, wherein one or more of the different types of simulated storage devices are selected based on characteristics of the different types of simulated storage devices.

5. The virtual machine of claim 2, wherein characteristics of the different types of simulated storage devices are obtained via a program interface in communication with the storage device emulation module.

6. The virtual machine of claim 2, wherein the storage device emulation module comprises at least one file describing characteristics of at least one storage device.

7. The virtual machine of claim 2, wherein characteristics of the different types of simulated storage devices are stored in at least one XML file.

8. The virtual machine of claim 2, wherein one or more of the different types of simulated storage devices discard the application specific data.

9. The virtual machine of claim 2, wherein characteristics associated with the at least one storage drive device comprises information associated with at least one of the group consisting of a storage drive device serial number, a manufacturer name, a barcode, a storage drive device model number, network address information, and a storage drive device manufacturer.

10. A method of simulating data storage operations with a virtual data agent comprising:

obtaining, by at least one virtual data agent executing on one or more computers, application specific data from an application executing on one or more of the computers, wherein the application specific data comprises different data formats; and

simulating the storage of the application specific data with a storage device emulation module executing in one or more computers, wherein the storage device emulation module comprises different types of simulated storage devices, wherein the different types of simulated storage devices simulate storage operations associated with one or more of the different data formats associated with the application specific data obtained by the virtual data agent.

11. The method of claim 10, further comprising selecting the different types of simulated storage devices based on the different data formats of the application specific data.

12. The method of claim 10, further comprising selecting one or more of the different types of simulated storage devices based on characteristics of the different types of simulated storage devices.

13. The method of claim 10, further comprising obtaining characteristics of the different types of simulated storage devices via a program interface in communication with the storage device emulation module.

14. The method of claim 10, wherein the storage device emulation module comprises at least one file describing characteristics of at least one storage device.

15. The method of claim 10, further comprising storing characteristics of the different types of simulated storage devices in at least one XML file.

16. The method of claim 10, further comprising discarding the application specific data sent to the one or more of the different types of simulated storage devices.

17. The method of claim 10, wherein characteristics associated with the at least one storage drive device comprises information associated with at least one of the group consisting of a storage drive device serial number, a manufacturer name, a barcode, a storage drive device model number, network address information, and a storage drive device manufacturer.
