Abstract

A cloud-based file system receives a subscription request associated with a networked device and identifying a set of one or more resources of the cloud-based file system and a set of one or more resource modifications. The cloud-based file system determines whether the networked device is authorized to access the resource, and, if so, records a subscription based on the subscription request. In response to a user, an application, or other suitable entity making a modification in the set of modifications to a resource in the set of resources, the cloud-based file system generates a notification to the networked device and to other networked devices with subscriptions that include the modification to the resource. The notification may identify the subscription with which the notification is associated, provide information identifying the modification, or provide other suitable information.

Claims

1. A computer-implemented method of notifying a networked device of a modification to a resource of a cloud-based file system, comprising:

receiving a subscription request associated with the resource and identifying the networked device;

in response to determining that the networked device is authorized to access the resource, recording a subscription based on the subscription request; and

in response to a modification being made to the resource, transmitting a notification regarding the modification to the networked device based on the recorded subscription.

2. The method of claim 1, wherein the subscription request is received from the networked device.

3. The method of claim 1, further comprising deleting the recorded subscription based on predetermined criteria.

4. The method of claim 3, wherein the predetermined criteria include reception of a subscription cancellation request from the networked device.

5. The method of claim 3, wherein the predetermined criteria include passage of a predetermined amount of time.

6. The method of claim 3, wherein the predetermined criteria include a failure to receive a predetermined message from the networked device within a predetermined amount of time of transmission of a notification to the networked device.

7. The method of claim 1, wherein the notification identifies the subscription with which the notification is associated.

8. The method of claim 1, wherein the notification identifies the modification.

9. The method of claim 1, further comprising transmitting, in response to recording the subscription, a subscription notification to the networked device.

10. The method of claim 9, wherein the subscription notification includes information regarding the status of the resource.

11. A cloud storage system, comprising:

a communication processor in communication with;

a resource database for storing a plurality of resources,

a subscription database for storing a plurality of subscriptions, wherein a subscription in the plurality of subscriptions identifies at least one resource characteristic, at least one type of modification, and at least one networked device, and

a subscription processor configured to;

store a first subscription in the subscription database based on a subscription request;

identify a modification to a resource with the at least one resource characteristic identified by the first subscription;

determine whether the modification is of the at least one type of modification identified by the first subscription; and

generate a notification to the at least one networked device identified by the first subscription;

wherein the communication processor is configured to;

transmit the notification to the at least one networked device.

12. The system of claim 11, wherein the subscription request is received from the at least one networked device identified by the first subscription.

13. The system of claim 11, further comprising deleting the first subscription based on predetermined criteria.

14. The system of claim 13, wherein the predetermined criteria include reception of a subscription cancellation request from the at least one networked device identified by the first subscription.

15. The system of claim 13, wherein the predetermined criteria include passage of a predetermined amount of time.

16. The system of claim 13, wherein the predetermined criteria include a failure to receive a predetermined message from the at least one networked device identified by the first subscription within a predetermined amount of time of transmission of a notification to the at least one networked device identified by the first subscription.

17. The system of claim 11, wherein the notification identifies the first subscription.

18. The system of claim 11, wherein the notification identifies the modification.

19. The system of claim 11, wherein the subscription processor is further configured to generate, in response to storing the first subscription, a subscription notification to the at least one networked device identified by the first subscription.

20. The system of claim 19, wherein the subscription notification includes information regarding the status of the resource.
