Abstract

What is disclosed is a volume access system. The volume access system includes a processing system configured to process at least a portion of each of a plurality of virtual disk files to generate an aggregate file system view that represents the plurality of virtual disk files as a single hierarchical data volume comprising a plurality of items within the plurality of virtual disk files. The volume access system also includes a network interface operatively coupled with the processing system and configured to communicate the aggregate file system view for traversal by a plurality of clients.

Claims

1. A volume access system, comprising:

a processing system configured to process at least a portion of each of a plurality of virtual disk files to generate an aggregate file system view that represents the plurality of virtual disk files as a single hierarchical data volume comprising a plurality of items within the plurality of virtual disk files; and

a network interface operatively coupled with the processing system and configured to communicate the aggregate file system view for traversal by a plurality of clients.

2. The volume access system of claim 1 wherein the plurality of items comprises a plurality of virtual machines and a plurality of data files associated with the plurality of virtual machines.

3. The volume access system of claim 1 wherein the aggregate file system view presents the signal hierarchical data volume as a mountable data volume.

4. The volume access system of claim 1 wherein at least one client of the plurality of clients comprises a backup utility configured to backup at least one of the plurality of virtual disk files.

5. The volume access system of claim 1 wherein the processing system is further configured to process at least a portion of each of a condensed backup file to generate a synthetic file system view of the condensed backup file, and wherein the aggregate file system view includes the synthetic file system view of the condensed backup file.

6. The volume access system of claim 1 wherein the network interface is further configured to provide access to the plurality of items within the plurality of virtual disk files in response to access requests communicated by the plurality of clients.

7. The volume access system of claim 6 wherein the plurality of access requests comprise a traversal operation on the single hierarchical data volume.

8. The volume access system of claim 7 wherein the traversal operation comprises an open operation, a read operation, a write operation, a delete operation, or a modify operation.

9. The volume access system of claim 7 wherein the traversal operation comprises a metadata operation.

10. The volume access system of claim 9 wherein the metadata operation comprises a folder navigation operation or a directory navigation operation.

11. One or more computer readable storage media having program instructions stored thereon for facilitating aggregate file system views of virtual environments that, when executed by a processing system, direct the processing system to at least:

obtain a first file system view of at least a virtual disk file, the first file system view comprising a first plurality of items within the virtual disk file;

obtain a second file system view of a condensed backup file, the second file system view comprising a second plurality of items within the condensed backup file; and

generate an aggregate file system view comprising the first file system view of the virtual disk file and the second file system view of the condensed backup file.

12. The one or more computer readable storage media of claim 11 wherein the first plurality of items within the virtual disk file comprises a first virtual machine and a first plurality of data items associated with the first virtual machine and identified in the first virtual disk file in accordance with a first native file system format.

13. The one or more computer readable storage media of claim 12 wherein the first file system view identifies the first virtual machine and the first plurality of data items in accordance with a synthetic file system format that is different than the first native file system format.

14. The one or more computer readable storage media of claim 11 wherein the condensed backup file comprises a backup of at least one of a plurality of virtual disk files.

15. The one or more computer readable storage media of claim 11 further comprising communicating the aggregate file system view over a network interface to a client device.

16. The one or more computer readable storage media of claim 11 wherein the aggregate file system view comprises a hierarchical ordering of the first plurality of items in the virtual disk file and the second plurality of items in the condensed backup file.

17. A method of operating a volume access system, the method comprising:

processing at least a condensed backup file to generate a file system view of the condensed backup file comprising a plurality of items within the condensed backup file;

providing the file system view of the condensed backup file over a network interface as a hierarchical data volume for a client device;

receiving over the network interface a file operation command generated on the client device for a target item of the hierarchical data volume;

in response to the file operation command, performing the file operation command on a first item of the plurality of items within the condensed backup file corresponding to the target item.

18. The method of claim 17, further comprising:

processing at least a virtual disk file associated with a live virtual machine to generate a file system view of the virtual disk file comprising a plurality of items within the virtual disk file;

providing an aggregate file system view over the network interface as the hierarchical data volume, wherein the aggregate file system view comprises the file system view of the condensed backup file and the file system view of the virtual disk file.

19. The method of claim 18 further comprising:

receiving over the network interface a second file operation command generated on the client device for a second target item of the hierarchical data volume;

in response to the second file operation command, performing the second file operation command on at least one of the plurality of items within the virtual disk file.

20. The method of claim 19 wherein the condensed backup file comprises a backup of the virtual disk file.
