Abstract

A computer-implemented method for protecting virtual machine data may include (1) receiving a request to perform a granular backup operation on data stored by a guest system within a virtual machine, (2) identifying a storage container that comprises an agent that performs backup operations, (3) attaching the storage container to the virtual machine in response to the request, and (4) performing the granular backup operation by sending an instruction to the guest system within the virtual machine to execute the agent. Various other methods, systems, and computer-readable media are also disclosed.

Claims

1. A computer-implemented method for protecting virtual machine data, at least a portion of the method being performed by a computing device comprising at least one processor, the method comprising:

receiving a request to perform a granular backup operation on data stored by a guest system within a virtual machine;

identifying a storage container provided for use by the virtual machine that comprises an agent that performs backup operations;

attaching the storage container to the virtual machine in response to the request;

performing the granular backup operation without writing the agent to the guest system within the virtual machine by sending an instruction to the guest system within the virtual machine to execute the agent from the storage container without installing the agent from the storage container to the guest system;

updating granular backup capabilities for the virtual machine without writing to the guest system within the virtual machine by;

receiving a subsequent request to perform a granular backup operation on data stored by the guest system within the virtual machine;

identifying a new storage container provided for use by the virtual machine that has replaced the storage container and that comprises an updated agent that performs backup operations;

attaching the new storage container instead of the storage container to the virtual machine.

2. The computer-implemented method of claim 1, further comprising attaching the storage container to at least one additional virtual machine to perform at least one additional granular backup operation on data stored by an additional guest system within the additional virtual machine.

3. The computer-implemented method of claim 1, further comprising attaching an additional instance of the storage container to at least one additional virtual machine to perform at least one additional granular backup operation on data stored by an additional guest system within the additional virtual machine.

4. The computer-implemented method of claim 1, wherein performing the granular backup operation comprises configuring the guest system to execute the agent after attaching the storage container to the virtual machine and before executing the agent.

5. The computer-implemented method of claim 1, wherein the agent collects metadata from within the guest system that describes backup data produced by the granular backup operation.

6. The computer-implemented method of claim 1, wherein the agent quiesces at least one application within the guest system to prepare data corresponding to the application for the granular backup operation.

7. The computer-implemented method of claim 1, further comprising detaching the storage container from the virtual machine in response to completing the granular backup operation.

8. The computer-implemented method of claim 1, wherein the granular backup operation comprises a granular restoration operation that restores data to the guest system within the virtual machine.

9. A system for protecting virtual machine data, the system comprising:

a receiving module that receives a request to perform a granular backup operation on data stored by a guest system within a virtual machine;

wherein the identification module further updates granular backup capabilities for the virtual machine without writing to the guest system within the virtual machine by;

receiving a subsequent request to perform a granular backup operation on data stored by the guest system within the virtual machine;

identifying a new storage container provided for use by the virtual machine that has replaced the storage container and that comprises an updated agent that performs backup operations;

attaching the new storage container instead of the storage container to the virtual machine;

the system further comprising at least one processor configured to execute the receiving module, the identification module, the attaching module, and the performing module.

10. The system of claim 9, wherein the attaching module is further programmed to attach the storage container to at least one additional virtual machine to perform at least one additional granular backup operation on data stored by an additional guest system within the additional virtual machine.

11. The system of claim 9, wherein the attaching module is further programmed to attach an additional instance of the storage container to at least one additional virtual machine to perform at least one additional granular backup operation on data stored by an additional guest system within the additional virtual machine.

12. The system of claim 9, wherein the performing module performs the granular backup operation by configuring the guest system to execute the agent after attaching the storage container to the virtual machine and before executing the agent.

13. The system of claim 9, wherein the agent collects metadata from within the guest system that describes backup data produced by the granular backup operation.

14. The system of claim 9, wherein the agent quiesces at least one application within the guest system to prepare data corresponding to the application for the granular backup operation.

15. The system of claim 9, wherein the performing module is further programmed to detach the storage container from the virtual machine in response to completing the granular backup operation.

16. The system of claim 9, wherein the granular backup operation comprises a granular restoration operation that restores data to the guest system within the virtual machine.

17. A non-transitory computer-readable-storage medium comprising one or more computer-readable instructions that, when executed by at least one processor of a computing device, cause the computing device to:
