Abstract

Embodiments include a recovery system, a computer-readable storage medium, and a method of recreating a state of a datacenter. The embodiments include a plurality of program modules that is executable by a processor to gather metadata from a first datacenter that includes at least one virtual machine (VM), wherein the metadata includes data representative of a virtual infrastructure of the first datacenter. The program modules are also executable by the processor to recreate a state of the first datacenter within a second datacenter using the metadata upon a determination that a failure occurred within the first datacenter, and to recreate the VM within the second datacenter.

Claims

1. A recovery system comprising:

a first datacenter comprising at least one virtual machine (VM);

a second datacenter;

at least one processor coupled to the first datacenter and to the second datacenter; and

a plurality of program modules that is executable by the at least one processor to;

gather metadata from the first datacenter, wherein the metadata includes data representative of a virtual infrastructure of the first datacenter;

recreate a state of the first datacenter within the second datacenter using the metadata upon a determination that a failure occurred within the first datacenter; and

replicate the at least one VM within the second datacenter.

2. The recovery system of claim 1, wherein the plurality of program modules comprises an extractor that gathers the metadata and organizes the metadata into a metadata package.

3. The recovery system of claim 2, wherein the recovery system further comprises at least one protection datastore, wherein the plurality of program modules comprises a protection daemon that receives the metadata package and stores the metadata package in the at least one protection datastore.

4. The recovery system of claim 3, wherein the recovery system further comprises at least one recovery datastore and a replication module that replicates the metadata package from the at least one protection datastore to the at least one recovery datastore.

5. The recovery system of claim 4, wherein the plurality of program modules further comprises a recovery agent that extracts the metadata from the metadata package replicated within the at least one recovery datastore.

6. The recovery system of claim 5, wherein the plurality of program modules further comprises a reconstructor that receives the metadata from the recovery agent and recreates a state of the first datacenter within the second datacenter.

7. The recovery system of claim 1, wherein the recovery system further comprises at least one datastore and wherein the first datacenter comprises at least one network, the plurality of program modules is executable by the at least one processor to gather network configuration data for the at least one network and store the network configuration data in the at least one datastore.

8. A computer-readable storage medium having computer-executable instructions embodied thereon, wherein, when executed by at least one processor, the computer-executable instructions cause the at least one processor to:

gather metadata from a first datacenter that includes at least one virtual machine (VM), wherein the metadata includes data representative of a virtual infrastructure of the first datacenter;

replicate the metadata and a state of the at least one VM to a second datacenter; and

recreate a state of the first datacenter within the second datacenter using the state of the at least one VM and the metadata upon a determination that a failure occurred within the first datacenter.

9. The computer-readable storage medium of claim 8, wherein the computer-executable instructions further cause the at least one processor to recreate the at least one VM within the second datacenter upon the determination that a failure occurred within the first datacenter.

10. The computer-readable storage medium of claim 8, wherein the computer-executable instructions further cause the at least one processor to gather metadata that further includes a list of components of the first datacenter.

11. The computer-readable storage medium of claim 8, wherein the computer-executable instructions further cause the at least one processor to package the metadata into a metadata package and store the metadata package in a first datastore coupled to the first datacenter.

12. The computer-readable storage medium of claim 11, wherein the computer-executable instructions further cause the at least one processor to transmit the metadata package to a second datastore coupled to the second datacenter.

13. The computer-readable storage medium of claim 8, wherein the first datacenter includes at least one network, and wherein the computer-executable instructions further cause the at least one processor to gather network configuration data for the at least one network and store the network configuration data in the first datastore.

14. A method of recreating a state of a datacenter, said method comprising:

gathering, by a processor, metadata from a first datacenter that includes at least one virtual machine (VM) and at least one network, wherein the metadata includes network configuration data for the at least one network;

storing the metadata and a state of the at least one VM within a first datastore coupled to the first datacenter; and

recreating, by a processor, a state of the first datacenter within a second datacenter using the metadata and the state of the at least one VM upon a determination that a failure occurred within the first datacenter.

15. The method of claim 14, further comprising replicating the at least one VM within the second datacenter upon the determination that a failure occurred within the first datacenter.

16. The method of claim 14, further comprising packaging the metadata into a metadata package by a first program module and storing the metadata package in the first datastore.

17. The method of claim 16, further comprising transmitting the metadata package from the first datastore to a second datastore coupled to the second datacenter.

18. The method of claim 17, further comprising extracting, by a second program module, the metadata from the metadata package within the second datastore when a failure of the first datacenter is determined to have occurred.

19. The method of claim 14, wherein the first datacenter includes a third datacenter, said method further comprising storing a state of the third datacenter within the first datastore.

20. The method of claim 19, further comprising recreating the state of the first datacenter and the state of the third datacenter upon the determination that a failure occurred within the first datacenter.
