Abstract

Methods, apparatus, systems to determine a distributed content storage scheme are disclosed. Example methods to store a content file include generating, with a processor remote from a first client device storing content shares of the content file, a first content share storage scheme identifying a second client device to which a first subset of a first combination of the content shares is to be distributed for storage when a first client device is coupled to a first local area network. The method further includes generating, with the processor, a second content share storage scheme identifying a third client device to which a first subset of a second combination of the content shares is to be distributed for storage when the first client device is coupled to a second local area network.

Claims

1. A method to store a content file, the method comprising:

generating, with a processor remote from a first client device storing content shares of the content file, a first content share storage scheme identifying a second client device to which a first subset of a first combination of the content shares is to be distributed for storage when a first client device is coupled to a first local area network; and

,

generating, with the processor, a second content share storage scheme identifying a third client device to which a first subset of a second combination of the content shares is to be distributed for storage when the first client device is coupled to a second local area network, the first and second combinations each having a threshold number of the content shares determined to be sufficient to reconstruct the content file, the threshold number being less than a total number of the content shares into which the content file was encoded and each of the threshold number of content shares being different content shares.

2. The method of claim 1 wherein the first combination and the second combination are a same combination.

3. The method of claim 1 wherein the first content share storage scheme indicates that a second subset of the first combination is to be retained on the first client device.

4. The method of claim 3 further comprising:

in response to an attempt by the second client device to access the content file, using the first content share storage scheme to determine that the second subset is stored on the first client device; and

instructing the second client device to retrieve the second subset of the first combination from the first client device.

5. The method of claim 3 further comprising:

in response to an attempt by the second client device to access the content file, determining whether the first client device is coupled to the first local area network;

if the first client device is coupled to the first local area network, instructing the second client device to retrieve the second subset of the first combination from the first client device; and

if the first client device not coupled to the first local area network, using the first content share storage scheme to determine whether the second subset of the first combination is stored on any other client device determined to be coupled to the first local area network.

6. The method of claim 4 further comprising:

receiving an indication that the second subset of the first combination has not been successfully retrieved from the first client device; and

accessing the first content share storage scheme to determine whether the first subset of the first combination is stored on any other client devices coupled to the first local area network.

8. The method of claim 1 wherein the first storage scheme indicates that the first client device is to retain all of the content shares, the method further comprising:

determining that a first of the content shares stored on the second client device has been corrupted; and

instructing the second client device to retrieve a copy of the first content share from the first client device.

7. (canceled)

9. An apparatus to store a content file, the apparatus comprising:

a memory having machine readable instructions stored thereon; and

a processor remote from a first client device storing content shares of the content file, the processor to execute the instructions to perform operations comprising;

generating a first content share storage scheme identifying a second client device to which a first subset of a first combination of the content shares is to be distributed for storage when the first client device is coupled to a first local area network; and

,

generating a second content share storage scheme identifying a third client device to which a first subset of a second combination of the content shares is to be distributed for storage when the first client device is coupled to a second local area network, the first and second combinations each having a threshold number of the content shares determined to be sufficient to reconstruct the content file, the threshold number being less than all of the content shares into which the content file was encoded.

10. The apparatus of claim 9 wherein the first combination and the second combination are a same combination.

11. The apparatus of claim 9 wherein the first content share storage scheme indicates that a second subset of the first combination is to be retained on the first client device.

12. The apparatus of claim 11 wherein the operations further comprise:

using the first content share storage scheme to determine that the second subset is stored on the first client device in response to an attempt by the second client device to access the content file; and

instructing the second client device to retrieve the second subset of the first combination from the first client device.

13. The apparatus of claim 11 wherein the operations further comprise:

determining whether the first client device is coupled to the first local area network in response to an attempt by the second client device to access the content file;

if the first client device is coupled to the first local area network, instructing the second client device to retrieve the second subset of the first combination from the first client device; and

if the first client device not coupled to the first local area network, using the first content share storage scheme to determine whether the second subset of the first combination is stored on any other client device determined to be coupled to the first local area network.

14. The apparatus of claim 12 wherein the operations further comprise:

receiving an indication that the second subset of the first combination has not been successfully retrieved from the first client device; and

accessing the first content share storage scheme to determine whether the first subset of the first combination is stored on any other client devices coupled to the first local area network.

17. A tangible machine readable storage medium comprising machine readable instructions which, when executed, cause a machine to perform operations comprising:

generating a first content share storage scheme identifying a first client device to which a first subset of a first combination of the content shares is to be distributed for storage when a second client device storing the content shares is coupled to a first local area network; and

generating a second content share storage scheme identifying a third client device to which a first subset of a second combination of content shares is to be distributed for storage when the second client device is coupled to a second local area network, the first and second combinations each having a threshold number of the content shares determined to be sufficient to reconstruct the content file, the threshold number being less than a total number of the content shares into which the content file was encoded and each of the threshold number of content shares being different content shares.

18. The tangible machine readable medium of claim 17 wherein the first combination and the second combination are a same combination.

19. The tangible machine readable medium of claim 17 wherein the first content share storage scheme indicates that a second subset of the first combination is to be retained on the second client device.

21. The tangible machine readable medium of claim 19 wherein the operations further comprise:

determining whether the second client device is coupled to the first local area network in response to an attempt by the first client device to access the content file; and
