Abstract

Embodiments of the present disclosure provide for a method and system for storing content based on one or more attributes associated with the content. Specifically, the present disclosure provides for determining storage capabilities of one or more storage devices associated with a computing device and also determining a retention policy associated with the content. In certain embodiments, the retention policy is identified by the one or more attributes. When the retention policy and the capabilities of the one or more storage devices have been determined, the content is written to the one or more storage devices based on the retention policy.

Claims

1. A method for storing content based on one or more attributes associated with the content, the method comprising:

determining storage capabilities of one or more storage devices associated with a computing device;

determining a retention policy associated with the content, wherein the retention policy is identified by the one or more attributes; and

writing the content to the one or more storage devices associated with the computing device based on the retention policy.

2. The method of claim 1, wherein writing the content to the computing device based on the retention policy comprises writing the content to the computing device using a first variable characteristic when a first retention policy is specified and writing the content to the computing device using a second variable characteristic when a second retention policy is specified.

3. The method of claim 1, wherein the retention policy defines a set period of time at which the content is to be retained.

4. The method of claim 1, wherein the computing device receives storage capabilities of one or more remote computing devices.

5. The method of claim 4, wherein the computing device receives the storage capabilities of the one or more remote computing devices during a session setup with the one or more remote computing devices.

6. The method of claim 1, further comprising tracking which segments of the one or more storage devices of the computing device the content has been written to.

7. The method of claim 1, further comprising sending a notification when a time period associated with the retention policy expires.

8. The method of claim 1, further comprising:

receiving a change to the retention policy; and

altering the retention policy without rewriting the content to the one or more storage devices associated with the computing device.

9. A computer-readable storage medium encoding computer executable instructions which, when executed by at least one processor, performs a method for storing content based on one or more attributes associated with the content, the method comprising:

determining storage capabilities of one or more storage devices associated with a computing device;

determining a retention policy associated with the content, wherein the retention policy is identified by the one or more attributes; and

writing the content to the one or more storage devices associated with the computing device based on the retention policy.

10. The computer-readable storage medium of claim 9, wherein writing the content to the computing device based on the retention policy comprises writing the content to the computing device using a first variable characteristic when a first retention policy is specified and writing the content to the computing device using a second variable characteristic when a second retention policy is specified.

11. The computer-readable storage medium of claim 9, wherein the retention policy defines a set period of time at which the content is to be retained.

12. The computer-readable storage medium of claim 9, wherein the computing device receives storage capabilities of one or more remote computing devices.

13. The computer-readable storage medium of claim 12, wherein the computing device receives the storage capabilities of the one or more remote computing devices during a session setup with the one or more remote computing devices.

14. The computer-readable storage medium of claim 9, further comprising instructions for tracking which segments of the one or more storage devices of the computing device the content has been written to

15. The computer-readable storage medium of claim 9, further comprising instructions for sending a notification when a time period associated with the retention policy expires.

16. The computer-readable storage medium of claim 9, further comprising instructions for:

receiving a change to the retention policy; and

altering the retention policy without rewriting the content to the one or more storage devices associated with the computing device.

17. A computing device comprising:

one or more processors; and

a memory coupled to the one or more processors, the memory for storing instructions which, when executed by the one or more processors, cause the one or more processors to perform a method for storing content based on one or more attributes associated with the content, the method comprising;

determining storage capabilities of one or more storage devices associated with the computing device;

determining a retention policy associated with the content, wherein the retention policy is identified by the one or more attributes; and

writing the content to the one or more storage devices associated with the computing device based on the retention policy, wherein writing the content to the one or more storage devices associated with the computing device based on the retention policy comprises writing the content to the one or more storage devices using a first variable characteristic when a first retention policy is specified and writing the content to the one or more storage devices using a second variable characteristic when a second retention policy is specified.

18. The system of claim 17, wherein the first variable characteristic and the second variable characteristic are dynamically selected based on the storage capabilities of the one or more storage devices and retention attributes of the one or more storage devices.

19. The system of claim 17, wherein the retention policy defines a set period of time for which the content is to be retained.

20. The system of claim 17, further comprising altering the retention policy based on a received request, wherein the retention policy is altered without re-writing the content.
