Techniques to replicate data using uploads from messaging clients

1. A computer-implemented method, comprising:

determining a sharing event for a data item, the sharing event associated with a source client device with a local storage of the data item;

determining that network storage of the data item is scheduled for relocation from a source storage device to a destination storage device;

requesting the source client device upload the data item to the destination storage device using upload network bandwidth of the source client device in response to the determination that network storage of the data item is scheduled for relocation; and

de-scheduling the relocation of the data item from the source storage device.

2. The method of claim 1 , wherein the data item is scheduled for relocation based on automated media messaging popularity prediction determining that the data item is predicted to have a high media messaging rate.

3. The method of claim 1 , the data item stored at a first data center, wherein the data item is scheduled for relocation based on a data center migration between the first data center and a second data center.

4. The method of claim 1 , the network storage associated with a messaging service, the sharing event corresponding to a messaging of the data item from the source client device to a destination client device using the messaging service.

5. The method of claim 1 , further comprising:

receiving a message package from the source client device, the message package comprising a data item hash of the data item and a storage length of the data item;

determining a data item identifier for the data item based on the data item hash and the storage length of the data item; and

identifying that the network storage contains the data item and that data item is scheduled for relocation based on the data item identifier.

6. The method of claim 5 , further comprising:

comparing the data item identifier to a data item reference record; and

identifying that the network storage contains the data item and that the data item is scheduled for relocation from the source storage device.

7. The method of claim 1 , further comprising:

receiving the data item at a destination storage device from the source client device;

receiving a download request for the data item from a destination client device;

retrieving the data item from the destination storage device; and

transmitting the data item to the destination client device.

8. An apparatus, comprising:

a processor circuit on a device;

a messaging server controller operative to determine a sharing event for a data item, the sharing event associated with a source client device with a local storage of the data item, and request the source client device upload the data item to a destination storage device in response to a determination that network storage of the data item is scheduled for relocation from a source storage device to the destination storage device using upload network bandwidth of the source client device; and

a storage management controller operative to determine that the network storage of the data item is scheduled for relocation from the source storage device and de-schedule the relocation of the data item from the source storage device.

9. The apparatus of claim 8 , wherein the data item is scheduled for relocation based on automated media messaging popularity prediction determining that the data item is predicted to have a high media messaging rate.

10. The apparatus of claim 8 , the data item stored at a first data center, wherein the data item is scheduled for relocation based on a data center migration between the first data center and a second data center.

11. The apparatus of claim 8 , the network storage associated with a messaging service, the sharing event corresponding to a messaging of the data item from the source client device to a destination client device using the messaging service.

12. The apparatus of claim 8 , further comprising:

the messaging server controller operative to receive a message package from the source client device, the message package comprising a data item hash of the data item and a storage length of the data item; and

the storage management controller operative to determine a data item identifier for the data item based on the data item hash and the storage length of the data item; and identify that the network storage contains the data item and that data item is scheduled for relocation based on the data item identifier.

13. The apparatus of claim 12 , further comprising:

the storage management controller operative to compare the data item identifier to a data item reference record and identify that the network storage contains the data item and that the data item is scheduled for relocation from the source storage device.

14. The apparatus of claim 8 , the download request comprising a resource locator, further comprising:

the messaging server controller operative to receive the data item at a destination storage device from the source client device, receive a download request for the data item from a destination client device, retrieve the data item from the destination storage device, and transmit the data item to the destination client device.

15. At least one non-transitory computer-readable storage medium comprising instructions that, when executed, cause a system to:

determine a sharing event for a data item, the sharing event associated with a source client device with a local storage of the data item;

determine that network storage of the data item is scheduled for relocation from a source storage device to a destination storage device;

request the source client device upload the data item to the destination storage device using upload network bandwidth of the source client device in response to the determination that network storage of the data item is scheduled for relocation; and

de-schedule the relocation of the data item from the source storage device.

16. The computer-readable storage medium of claim 15 , wherein the data item is scheduled for relocation based on automated media messaging popularity prediction determining that the data item is predicted to have a high media messaging rate.

17. The computer-readable storage medium of claim 15 , the data item stored at a first data center, wherein the data item is scheduled for relocation based on a data center migration between the first data center and a second data center.

18. The computer-readable storage medium of claim 15 , the network storage associated with a messaging service, the sharing event corresponding to a messaging of the data item from the source client device to a destination client device using the messaging service.

19. The computer-readable storage medium of claim 15 , comprising further instructions that, when executed, cause a system to:

receive a message package from the source client device, the message package comprising a data item hash of the data item and a storage length of the data item;

determine a data item identifier for the data item based on the data item hash and the storage length of the data item; and

identify that the network storage contains the data item and that data item is scheduled for relocation based on the data item identifier.

20. The computer-readable storage medium of claim 15 , the download request comprising a resource locator, comprising further instructions that, when executed, cause a system to:

receive the data item at a destination storage device from the source client device;

receive a download request for the data item from a destination client device;

retrieve the data item from the destination storage device; and

transmit the data item to the destination client device.
