Shared community storage network
View Patent ↗A hardware and/or software facility for durably and securely storing data within a shared community storage network. A user may have a storage device that they intend to share with others in the network. All or a portion of the storage device is registered with the community storage network as a storage node. Once registered with the network, third party data may be stored on the storage node and remotely accessed by third parties. In addition, data stored on the storage device by the user may be stored in the shared community storage network by encrypting the data, adding redundancy, and distributing it to other storage nodes within the storage network. Data that is stored in the storage network is accessible to the user even if their storage device is inaccessible or fails.

16. The method of claim 15 , wherein the storage is measured by the storage space consumed by third parties in the identified storage space.
17. The method of claim 13 , wherein the data is stored in the identified storage space in an encrypted format.
18. The method of claim 13 , wherein the data is stored in the identified storage space in a redundant fashion.
19. The method of claim 13 , wherein a data file from a third party is fragmented and stored across two or more of the plurality of unaffiliated storage devices.
20. The method of claim 1 , wherein the available storage space is less than a total capacity of the plurality of unaffiliated storage devices.
21. The method of claim 1 , wherein the third parties to which the identified storage space is made available only includes those third parties that have offered to associate a storage device that they host with the network-accessible service.
22. A method of operating a reliable network storage service constructed from a plurality of unreliable storage devices, the method comprising:
aggregating available storage space on a plurality of storage devices,hosted by geographically-dispersed entities, each of the plurality of storage devices accessed via a Wide Area Network (WAN) and having no service level guarantee;
offering the aggregated storage space comprised of the plurality of storage devices having no service level guarantee to third parties as a network storage service for storing data, the network storage service being offered with a service level guarantee;
coordinating the storage of third party data in the network storage service, wherein third party data is stored in an encrypted and redundant fashion;
monitoring usage information of each of the plurality of storage devices, the usage information reflecting the use of the plurality of storage devices by third parties; and
charging the third parties in accordance with the determined usage information.
23. The method of claim 22 , wherein the geographically-dispersed entities are non-commercial entities.
24. The method of claim 23 , wherein the non-commercial entities are households.
25. The method of claim 23 , wherein a storage device hosted by the household is partitioned to contain household data and third party data.
26. The method of claim 23 , wherein each non-commercial entity is compensated in proportion to the use of their storage device in the network-accessible storage service.
27. The method of claim 26 , wherein the compensation is monetary compensation.
28. The method of claim 26 , wherein the compensation is non-monetary compensation.
29. The method of claim 28 , wherein the non-monetary compensation is selected from a set consisting of backup services, award points, and file-sharing.
30. The method of claim 22 , wherein the service level guarantee is availability.
31. The method of claim 22 , wherein the service level guarantee is performance.
32. The method of claim 22 , wherein the service level guarantee is security.
33. The method of claim 22 , wherein the usage information is the bandwidth consumed by third parties in storing data to and retrieving data from the plurality of storage devices.
34. The method of claim 22 , wherein the usage information is the storage space consumed by third parties in storing data in the plurality of storage devices.
35. The method of claim 22 , wherein a data file from a third party is fragmented and stored across two or more of the plurality of unaffiliated storage devices.
