Abstract

Techniques are described for extending public or enterprise cloud storage systems with private end user devices, such as laptops, personal computers and the like. The system allows users to register their own personal (i.e., private) devices as storage extensions to the cloud storage system. Once a user has registered their device as an extension to the cloud storage system, that device becomes available as a storage location and can be made accessible via the graphical user interface (GUI) provided by the cloud storage system. Thereafter, any user that has been granted permissions to the content is able to access the content stored on the extension device.

Claims

1. A method for extending a public cloud storage system with private devices, said method comprising:

receiving, from an agent operating on a first private device, a request to register the first private device as an extension to the public cloud storage system, the public cloud storage system including one or more public cloud storage servers storing content;

registering the first private device as the extension to the public cloud storage system;

determining an access control list (ACL) for one or more files on the first private device based on information received from the agent on the first private device, the ACL specifying reading and writing permissions for the one or more files;

receiving, by the public cloud storage system, a request from a second private device to access content that is available to the second private device;

determining a subset of the content stored on the one or more public cloud storage servers that is available for access to the second private device;

determining, by the public cloud storage system, whether the ACL grants the second private device access to the one or more files stored on the first private device registered as the extension to the public cloud storage system; and

in response to determining that the ACL grants the second private device access to the one or more files;

providing a graphical user interface (GUI) that enables the second private device to access both (a) the subset of the content stored on the one or more public cloud storage servers and (b) the one or more files stored on the first private device.

2. The method of claim 1, wherein the first private device corresponds to a first user and the second private device corresponds to a second user and wherein the first user grants the second user access to the one or more files by indicating the second user in the ACL.

3. The method of claim 1, wherein the agent is a software program that is downloaded and installed on the first private device to enable the first private device to be registered as the extension to the public cloud storage system.

4. The method of claim 1, further comprising:

in response to receiving the request from the second private device,

determining, based on the ACL, a plurality of private devices that store content available to be accessed by the second private device; and

displaying, in the GUI, the content stored on the plurality of private devices that is available to be accessed by the second private device.

5. The method of claim 1, wherein the first private device is configured to maintain a stable network connection with the one or more public cloud storage servers after being registered as the extension to the public cloud storage system.

6. The method of claim 1, further comprising:

receiving, by the one or more public cloud storage servers, a request from the first private device to view content that is available for access to the first private device;

determining a subset of the content stored on the one or more public cloud storage servers that is available for access to the first private device; and

providing a graphical user interface (GUI) to the first private device, the GUI configured to enable the first private device to access the subset of the content stored on the one or more public cloud storage servers that is available for access to the first private device.

7. The method of claim 1, wherein the agent on the first private device provides an interface to enable the first private device to set one or more extension storage settings, the extension storage settings including one or more of:

a maximum Input/Output (I/O) speed limit for other private devices accessing content on the first private device;

maximum storage space that is accessible by other private devices on the first private device;

an administrative account and password; and

a backup strategy for content on the first private device.

8. A computing device, comprising:

at least one processor; and

memory including instructions that, when executed by the at least one processor, cause the computing device to;

receive, from an agent operating on a first private device, a request to register the first private device as an extension to a cloud storage system, the cloud storage system including one or more cloud storage servers storing content;

register the first private device as the extension to the cloud storage system;

determine an access control list (ACL) for one or more files on the first private device based on information received from the agent on the first private device, the ACL specifying reading and writing permissions for the one or more files;

receive, by the cloud storage system, a request from a second private device to access content that is available to the second private device;

determine a subset of the content stored on the one or more cloud storage servers that is available for access to the second private device;

determine, by the cloud storage system, whether the ACL grants the second private device access to the one or more files stored on the first private device registered as the extension to the cloud storage system; and

in response to determining that the ACL grants the second private device access to the one or more files;

provide a graphical user interface (GUI) that enables the second private device to access both (a) the subset of the content stored on the one or more cloud storage servers and (b) the one or more files stored on the first private device.

9. The computing device of claim 8, wherein the first private device corresponds to a first user and the second private device corresponds to a second user and wherein the first user grants the second user access to the one or more files by indicating the second user in the ACL.

10. The computing device of claim 8, wherein the agent is a software program that is downloaded and installed on the first private device to enable the first private device to be registered as the extension to the cloud storage system.

11. The computing device of claim 8, the memory further comprising instructions, that when executed by the at least one processor, cause the computing device to:

in response to receiving the request from the second private device,

determine, based on the ACL, a plurality of private devices that store content available to be accessed by the second private device; and

display, in the GUI, the content stored on the plurality of private devices that is available to be accessed by the second private device.

12. The computing device of claim 8, wherein the first private device is configured to maintain a stable network connection with the one or more cloud storage servers after being registered as the extension to the cloud storage system.
