Abstract

According to one embodiment, a method is disclosed for storing and archiving point-in-time sets of a raw data set in an environment including at least one server storing the raw data set. The method includes providing a virtualization layer on a computing resources pool. A virtualized storage application is operated on the virtualization layer. The virtualization layer shields the virtualized storage application from actual hardware in the computing resources pool. Storage efficient versions of the raw data set stored on one or more servers are generated. The storage efficient versions of the raw data set include point-in-time versions of the raw data set that are smaller in size than the raw data set.

Claims

1. In an environment including at least one server storing a raw data set, a method for storing and archiving point-in-time sets of the raw data set, the method comprising:

providing a virtualization layer on a computing resources pool;

operating a virtualized storage application on the virtualization layer, the virtualization layer shielding the virtualized storage application from actual hardware in the computing resources pool, wherein the virtualized storage application generates storage efficient versions of a raw data set, wherein the storage efficient versions include point-in-time versions of the raw data set that are smaller in size than the raw data set; and

storing the virtualized storage application and the storage efficient versions of the raw data set to an archive data mechanism, wherein the virtualized storage application and the storage efficient versions of the raw data are restorable to hardware that supports the virtualized storage application.

2. The method of claim 1, wherein the archive data mechanism comprises a second virtualized storage application.

3. The method of claim 2, further comprising recovering the raw data set at a particular point-in-time using a new virtualized storage application on a different virtualization layer.

4. The method of claim 2, further comprising recovering the raw data set at a particular point-in-time using the virtualized storage application.

5. The method of claim 3, wherein the new virtualized storage application is generated from the virtualized storage application stored in the archive data mechanism.

6. The method of claim 1, further comprising porting the virtualized storage application onto a new hardware subsystem, wherein the new hardware subsystem does not match a hardware system of the computing resources pool.

7. The method of claim 1, wherein generating storage efficient versions of the raw data set comprises employing one or more of snapshots, file differencing techniques, content addressed storage systems, or continuous data protections systems.

8. The method of claim 1, further comprising encapsulating the virtualized storage application into a file such that a full system including fully configured applications, operating system, BIOS and virtual hardware can be moved from one physical server to another.

9. A system for archiving data, the system comprising:

a storage device storing a raw data set;

a computer architecture communicably coupled to the storage device upon which a first storage application runs and generates a plurality of versions of the raw data set, the first storage application being run on a virtualization layer on the computer architecture;

an archive storage mechanism communicably coupled to the computer architecture for storing the plurality of versions of the raw data set and the first storage application as a virtualized system in the archive storage mechanism, the virtualized system including the first storage application and the plurality of versions of the raw data set; and

a hardware subsystem communicably coupled to the archive storage mechanism, wherein a recovered version of the raw data set based on the plurality of versions of the raw data set is generated by a second storage application operating on the virtualization layer operating on the hardware subsystem.

10. The system of claim 9, further comprising a plurality of storage applications.

11. The system of claim 9, wherein the virtualization layer presents a normalized representation of the computer architecture and shields the storage device from the computer architecture.

12. The system of claim 9, wherein the first storage application, the second storage application, or both, include one or more of:

a storage module for generating versions of the raw data set that are reduced in size;

or

a recovery module for generating a recovered version of the raw data set.

13. The system of claim 9, further comprising an operating system associated with the first storage application, the second storage application, or both.

14. The system of claim 13, wherein the operating system comprises one or more of:

Windows;

Linux;

Novell;

Solaris;

or FreeBSD.

15. The system of claim 9, wherein the second storage system comprises the first storage application after the virtualization system, which includes the first storage application and the raw data set, is ported from the archive storage mechanism to the hardware subsystem.
