Metadata storage in unused portions of a virtual disk file
View Patent ↗Embodiments disclosed herein provide systems and method for storing metadata to unused portions of a virtual disk file. In a particular embodiment, a method provides selecting a virtual disk file stored on a data storage volume and identifying unused portions of the virtual disk file. The method further provides writing metadata for the virtual disk file in the unused portions of the virtual disk file.
1. A method of operating a computing system to handle a virtual disk file, comprising:
utilizing the virtual disk file in accordance with metadata for the virtual disk file, wherein the virtual disk file has the metadata stored within unused portions of the virtual disk file.
2. The method of claim 1 , wherein utilizing the virtual disk file comprises:
migrating the virtual disk file to the computing system.
3. The method of claim 1 , further comprising:
analyzing the virtual disk file to retrieve the metadata from within the unused portions of the virtual disk file.
4. The method of claim 1 , wherein the metadata describes the virtual disk file and a virtual environment for the virtual disk file.
5. The method of claim 1 , wherein the virtual disk file comprises a Virtual Machine Disk (VMDK) file format.
6. A system to handle a virtual disk file, the system comprising:
one or more computer readable storage media;
a processing system operatively coupled with the one or more computer readable storage media; and
program instructions stored on the one or more computer readable storage media that, when read and executed by the processing system, direct the processing system to:
utilize the virtual disk file in accordance with metadata for the virtual disk file, wherein the virtual disk file has the metadata stored within unused portions of the virtual disk file.
7. The system of claim 6 , wherein to utilize the virtual disk file the program instructions direct the processing system to:
migrate the virtual disk file to the computing system.
8. The system of claim 6 , wherein the program instructions further direct the processing system to:
analyze the virtual disk file to retrieve the metadata from within the unused portions of the virtual disk file.
9. The system of claim 6 , wherein the metadata describes the virtual disk file and a virtual environment for the virtual disk file.
10. The system of claim 6 , wherein the virtual disk file comprises a Virtual Machine Disk (VMDK) file format.
