Abstract

Techniques are disclosed for a device that presents a mass storage device to a computing environment, and which stores data written to the device by the computer in a network storage service. The device also presents files stored in the network storage service to the computer as though those files were stored on a mass storage device.

4. The method of claim 2, further comprising writing, by the device, the data to a memory of the device after receiving the indication of the data.

5. The method of claim 4, wherein writing the data to the first memory of the device comprises:

encrypting, by the device, the data; and

writing the data to the first memory of the device.

6. The method of claim 5, further comprising:

receiving, by the device, an encryption key from the network-accessible storage service; and

wherein encrypting, by the device, the data comprises encrypting the data with the encryption key.

7. The method of claim 6, further comprising communicating, by the device, with the computing device according to a storage device protocol.

8. A non-transitory computing device-readable medium, bearing computing device-executable instructions that, when executed on a computing device, cause the computing device to perform operations comprising:

determining that a device is coupled to a second computing device via a physical connector;

establishing a communication channel with a network-accessible storage service;

receiving an identification of a first file from the network-accessible storage service via the communication channel; and

transmitting the identification of the first file to the second computing device via the physical connector, wherein the identification of the first file is translated from a format used by the network-accessible storage service to a block-based format used by a computing environment of the second computing device, and wherein the translated identification, as transmitted by the computing device, presents the first file as part of the computing environment when interpreted by an existing file system driver of the computing environment.

9. The non-transitory computing device-readable medium of claim 8, further bearing computing device-executable instructions that, when executed on a computing device, cause the computing device to perform operations comprising:

receiving an indication from the second computing device of data from the computing device to write to the device;

translating the data from the block-based format to the format used by the network-accessible storage service; and

sending the translated data in the format used by the network-accessible storage service to the network-accessible storage service via the communication channel.

10. The non-transitory computing device-readable medium of claim 9, wherein sending the translated data in the format used by the network-accessible storage service to the network-accessible storage service via the communication channel comprises:

sending the network-accessible storage service a PUT request identified in a Hypertext Transfer Protocol (HTTP) file in a Representational State Transfer (REST) application programming interface (API) call.

11. The non-transitory computing device-readable medium of claim 8, wherein establishing, by the device, the communication channel with the network-accessible storage service comprises:

sending, by the device, an identifier to the network-accessible storage service that uniquely identifies the device among all devices authorized by the network-accessible storage service.

12. The non-transitory computing device-readable medium of claim 8, wherein establishing, by the device, the communication channel with the network-accessible storage service comprises:

sending, by the device, an identifier to the network-accessible storage service that uniquely identifies a user account associated with the device among all user accounts authorized by the network-accessible storage service.

13. The non-transitory computing device-readable medium of claim 8, wherein receiving the identification of the first file from the network-accessible storage service via the communication channel comprises:

sending the network-accessible storage service a request for a listing of files associated with a user account identified in the request.

14. The non-transitory computing device-readable medium of claim 8, further bearing computing device-executable instructions that, when executed on a computing device, cause the computing device to perform operations comprising:

receiving an indication of data to be written from the second computing device;

sending a version of the data translated into the format used by the network-accessible storage service to the network accessible storage service via the communication channel; and

caching at least a portion of the data in the block-based format in a second memory.
