Abstract

Systems, methods, and computer program products are provided for instant recovery of a virtual machine (VM) from a compressed image level backup without fully extracting the image level backup file'"'"'s contents to production storage. The method receives restore parameters and initializes a virtual storage. The method attaches the virtual storage to a hypervisor configured to launch a recovered VM. The method stores virtual disk data changes inflicted by a running operating system (OS), applications, and users in a changes storage. The method provides the ability to migrate the actual VM disk state (taking into account changed disk data blocks accumulated in changes storage) so as to prevent data loss resulting from the VM running during the recovery and accessing virtual storage, to production storage without downtime. In embodiments, the method displays receives restore parameters in an interactive interface and delivers the recovery results via an automated message, such as an email message.

Claims

1. A system for recovering a virtual machine, comprising:

a restore operator console configured to receive a selection of an image level backup of the virtual machine and a data object of the image level backup;

a data conversion engine configured to determine a data portion of the image level backup containing the data object and to perform content translation on the image level backup to extract contents of the data portion;

a storage configured to receive the extracted contents of the data portion from the data conversion engine and to represent the extracted contents to a server; and

one or more processors configured to execute at least one of;

the restore operator console, the data conversion engine, and the storage.

2. The system of claim 1, wherein the data conversion is further configured to translate the contents from an image level backup tile format to a second format.

3. The system of claim 2, wherein the second format corresponds to a native format of the server.

4. The system of claim 1, wherein the data conversion engine is further configured to perform at least one of:

decompression, de-duplication, an decryption on the image level backup to extract the contents of the data portion.

5. The system of claim 1, wherein the extracted contents of the data portion include raw data.

6. The system of claim 1, wherein the data conversion engine is further configured to perform content translation on the image level backup to extract the contents of the data portion without fully extracting the image level backup.

7. The system of claim 1, further comprising:

a changes storage configured to store data changes to a virtual disk of the virtual machine, the data changes caused by the server writing to the storage.

8. The system of claim 7, further comprising:

a recovery finalization module, communicatively coupled to the server, configured to perform recovery of the virtual machine from the image level backup and the changes storage according to restore parameters.

9. The system of claim 8, wherein the recovery finalization module is further configured to switch the virtual machine from using the storage to using a production storage.

10. The system of claim 1, wherein the data object includes a virtual disk image or a configuration file associated with the virtual machine.

11. The system of claim 1, wherein the image level backup backs up a plurality of data blocks from the storage, and the selection of the data object specifies at least one of the plurality of data blocks to restore.

12. The system of claim 1, wherein the server is a hypervisor.

13. A method for recovering a virtual machine, comprising:

receiving a selection of an image level backup of the virtual machine and a data object of the image level backup;

determining a data portion of the image level backup containing the data object;

performing content translation on the image level backup to extract contents of the data portion; and

representing the extracted contents to a server.

14. The method of claim 13, further comprising:

translating the contents from an image level backup file format to a second format.

15. The method of claim 14, wherein the second format corresponds to a native format of the server.

16. The method of claim 13, further comprising:

performing at least one of;

decompression, de-duplication, an decryption on the image level backup to extract the contents of the data portion.

17. The method of claim 13, wherein the extracted contents of the data portion include raw data.

18. The method of claim 13, further comprising:

performing content translation on the image level backup to extract the contents of the data portion without fully extracting the image level backup.

19. The method of claim 13, wherein the image level backup backs up a plurality of data blocks from the storage, and the selection of the data object specifies at least one of the plurality of data blocks to restore.

20. The method of claim 13, wherein the server is a hypervisor.

21. A non-transitory computer-readable medium having instructions stored thereon that, when executed by one or more processors, cause the one or more processors to perform a method for recovering a virtual machine, the method comprising:

receiving a selection of an image level backup of the virtual machine and a data object of the image level backup;

determining a data portion of the image level backup containing the data object;

performing content translation on the image level backup to extract contents of the data portion; and

representing the extracted contents to a server.

22. The non-transitory computer-readable medium of claim 21, wherein the method further comprises:

translating the contents from an image level backup file format to a second format.

23. The non-transitory computer-readable medium of claim 22, wherein the second format corresponds to a native format of the server.

24. The non-transitory computer-readable medium of claim 21, wherein the method further comprises:

performing at least one of;

decompression, de-duplication, an decryption on the image level backup to extract the contents of the data portion.

25. The non-transitory computer-readable medium of claim 21, wherein the extracted contents of the data portion include raw data.

26. The non-transitory computer-readable medium of claim 21, further comprising:

performing content translation on the image level backup to extract the contents of the data portion without fully extracting the image level backup.

27. The non-transitory computer-readable medium of claim 21, wherein the image level backup backs up a plurality of data blocks from the storage, and selection of the data object specifies at least one of the plurality of data blocks to restore.

28. The non-transitory computer-readable medium of claim 21, wherein the server is a hypervisor.
