Abstract

A storage device configured to join a shared community storage 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 a 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. The user may receive economic or non-economic incentives for allowing the storage device to join the shared community storage network.

Claims

1. A storage device configured to join a network-accessible storage service comprised of a plurality of unaffiliated and un-trusted storage nodes, the storage device comprising:

a storage medium configured to store data electronically;

a network communication component configured to detect a connection with a wide area network (WAN) and further configured to send and receive data via the WAN;

a registration component coupled to the network communication component and configured to transmit a registration request across the WAN to a storage service management node, the registration request offering to make at least a portion of the storage medium accessible to the network-accessible storage service comprised of a plurality of unaffiliated and un-trusted storage nodes under terms that do not require any level of guaranteed service from the storage device to maintain the accessibility of at least the portion of the storage medium to the network-accessible storage service, the registration component being configured to receive a confirmation from the storage service management node in response to the offer to make at least a portion of the storage medium accessible being accepted by the storage service management node; and

an access manager coupled to the network communication component and configured to, after the registration component receives the confirmation from the storage service management node, receive data across the WAN from a client device that utilizes the network-accessible storage service, the access manager being configured to store the received data in the storage medium, wherein the received data is encrypted prior to receipt so that the received data is not readily accessible to the host of the storage device and wherein the network-accessible storage service increases the number of unaffiliated and un-trusted storage nodes at which a data object is stored to account for increases in the number of unreliable storage nodes associated with the network-accessible storage service and decrease the probability that all of the storage nodes storing the data object are compromised.

2. The storage device of claim 1, wherein the registration request is automatically transmitted by the registration component when the network communication component detects a connection with a WAN.

3. The storage device of claim 1, wherein the registration request is transmitted by the registration component as a result of a registration process undertaken by the host of the storage device.

4. The storage device of claim 1, wherein the registration request offers to associate all of the storage medium with the network-accessible storage service.

5. The storage device of claim 1, wherein the access manager is further configured to, after the registration component receives the confirmation from the storage service management node, transmit data across the WAN to a client device that utilizes the network-accessible storage service, the transmitted data being previously stored in the storage medium in encrypted form and being transmitted in response to a read request from the client device.

6. The storage device of claim 1, wherein at least a portion of the storage medium is used to store data that is accessible to the host of the storage device.

7. The storage device of claim 6, wherein the access manager is further configured to, after the registration component receives the confirmation from the storage service management node, transmit data across the WAN to two or more of a plurality of unaffiliated storage nodes that enable the network-accessible storage service, the transmitted data being previously stored in the storage medium by the host and wherein the data is being transmitted for purposes of backing-up the data.

8. The storage device of claim 1, wherein the level of guaranteed service relates to availability.

9. The storage device of claim 1, wherein the level of guaranteed service relates to performance.

10. The storage device of claim 1, wherein the access manager further monitors a size of received data that is stored in the storage medium and periodically transmits the size to the storage service management node.

11. The storage device of claim 1, wherein the access manager further monitors a bandwidth consumed by receiving data that is stored in the storage medium, and periodically transmits the bandwidth consumed to the storage service management node.

12. The storage device of claim 1, wherein the received data represents only a portion of a data object and the other portions of the data object are stored on other unaffiliated storage nodes.

13. The storage device of claim 1, wherein the registration request further includes an identifier associated with the storage device.

14. The storage device of claim 1, wherein the registration request further includes an indication of a characteristic of the storage device.

15. The storage device of claim 14, wherein the characteristic is selected from a set consisting of processing capability, storage capability, input/output capability, connection bandwidth, and geographic location.

16. A method of joining a storage device to a network-accessible storage service comprised of a plurality of unaffiliated and un-trusted storage nodes, the method comprising:

connecting a storage device to a wide area network (WAN), the storage device including a storage medium for electronically storing data;

transmitting a registration request across the WAN to a storage service management node, the registration request offering to make at least a portion of the storage medium in the storage device with accessible to a network-accessible storage service comprised of a plurality of unaffiliated and un-trusted storage nodes under terms that do not require any level of guaranteed service from the storage device to maintain the accessibility of at least a portion of the storage medium to the network-accessible storage service when the storage device is connected to the WAN;

receiving a confirmation from the storage service management node in response to the offer to make at least a portion of the storage medium accessible being accepted by the storage service management node;

after receiving the confirmation from the storage service management node, receiving data across the WAN from a client device that utilizes the network-accessible storage service and wherein the network-accessible storage service increases the number of unaffiliated and un-trusted storage nodes at which a fragment of a data object is stored to account for increases in the number of unreliable storage nodes associated with the network-accessible storage service and decrease the probability that all of the storage nodes storing the fragment of the data object are compromised; and

storing the received data in the storage medium, the received data being encrypted prior to receipt so that the received data is not readily accessible to a host of the storage device.

17. The method of claim 16, wherein the registration request is automatically transmitted when the storage device is connected to the WAN.

18. The method of claim 16, wherein the registration request is transmitted as a result of a registration process undertaken by the host of the storage device.

19. The method of claim 16, wherein the registration request offers to associate all of the storage medium with the network-accessible storage service.
