Abstract

One example method includes discovering an application instance on a host, reporting the existence of the application instance, discovering application components of the application instance, and mapping the application components to information concerning an underlying filesystem and information concerning an underlying physical drive. The example method additionally includes freezing the application instance in response to a first instruction, and then thawing the application instance in response to a second instruction.

Claims

1. A method, comprising:

discovering all copies of an application running on a host;

reporting the number of copies of the application that were discovered;

discovering application components of one copy of the application;

mapping the application components to a storage volume;

freezing the one copy of the application in response to a first instruction;

making a new copy of the application by copying the application components that are in the storage volume; and

thawing the one copy of the application in response to a second instruction.

2. The method as recited in claim 1, further comprising running the new copy of the application.

3. The method as recited in claim 1, wherein the method is performed by an application-aware agent that has been pushed to the host.

4. The method as recited in claim 1, wherein the host is a virtual machine (VM).

5. The method as recited in claim 1, wherein existence of the copies of the application is reported to a copy management application.

6. The method as recited in claim 1, wherein the first instruction and the second instruction are received from a copy management application.

7. The method as recited in claim 1, wherein discovery of the application components of the one copy of the application is performed in response to a request from a copy management application.

8. A non-transitory storage medium having stored therein computer-executable instructions which, when executed by one or more hardware processors, perform operations comprising:

discovering all copies of an application running on a host;

reporting the number of copies of the application that were discovered;

discovering application components of one copy of the application;

mapping the application components to a storage volume;

freezing the one copy of the application in response to a first instruction;

making a new copy of the application by copying the application components that are in the storage volume; and

thawing the one copy of the application in response to a second instruction.

9. The non-transitory storage medium as recited in claim 8, wherein the operations further comprise running the new copy of the application.

10. The non-transitory storage medium as recited in claim 8, wherein the operations are performed by an application-aware agent that has been pushed to the host.

11. The non-transitory storage medium as recited in claim 8, wherein the host is a virtual machine (VM).

12. The non-transitory storage medium as recited in claim 8, wherein existence of the copies of the application is reported to a copy management application.

13. The non-transitory storage medium as recited in claim 8, wherein the first instruction and the second instruction are received from a copy management application.

14. The non-transitory storage medium as recited in claim 8, wherein discovery of the application components of the one copy of the application is performed in response to a request from a copy management application.

15. A computing device comprising:

one or more hardware processors; and

the non-transitory storage medium as recited in claim 8.

16. A method, comprising:

pushing an application-aware agent to a host;

receiving, from the application-aware agent, a report identifying the number of copies of an application residing at the host;

subscribing to a service plan that specifies parameters of a copy that is to be made of the application;

requesting discovery of application components of one of the copies of the application that resides at the host;

receiving a map of the application components to information concerning an underlying filesystem and information concerning an underlying physical drive;

mapping a physical drive identified in the information concerning the underlying physical drive to a storage volume;

sending an instruction to freeze the application;

making a copy of the application; and

sending an instruction to thaw the application.

17. The method as recited in claim 16, wherein the instructions to freeze and thaw the application are sent to the application-aware agent.

18. The method as recited in claim 16, wherein the application-aware agent is pushed to the host in response to a command from a tenant.

19. The method as recited in claim 16, wherein the map of the application components to information concerning an underlying filesystem and information concerning an underlying physical drive is received from the application-aware agent.

20. The method as recited in claim 16, further comprising cataloging information concerning the copy of the application, and marking copy creation as done.
