Abstract

A redundant cloud storage solution may be created from individual cloud storage solutions. Files may be split into pieces and stored in separate cloud storage solutions and then retrieved from the cloud storage solutions to assemble the original ale. When splitting the files, the data may be encrypted for additional security. Additionally, redundancy may be obtained by duplicating data across multiple cloud storage solutions, such as in a RAID level 5 configuration. A server may intervene between a client device and the cloud storage solutions to perform the file splitting, encrypting, and management functions. Thus, the client access to the redundant cloud solution may function as any other network drive.

Claims

1. A method, comprising:

receiving a file for remote storage;

splitting the file into a first part and a second part;

encrypting the first part and the second part;

uploading the encrypted firs part to a first cloud storage solution; and

uploading the encrypted second part to a second cloud storage solution.

2. The method of claim 1, in which the first cloud storage solution is different from the second cloud storage solution.

3. The method of claim 1, further comprising:

receiving a request for the file;

retrieving the first part from the first cloud storage solution;

retrieving the second part from the second cloud storage solution; and

transmitting the first part and the second part in response to the request.

4. The method of claim 3, further comprising:

combining the first part and the second part; and

encrypting the combined first and second part before the step of transmitting the first part and the second part.

5. The method of claim 3, further comprising:

receiving an update for the file; and

updating the first part and the second part corresponding to the update.

6. The method of claim 1, further comprising:

receiving metadata related to the file; and

storing the metadata in a database server to the file.

7. The method of claim 1, in which the file is received from a mobile app on a mobile device.

8. A computer program product, comprising:

a non-transitory computer readable medium comprising

code to receive a file for remote storage;

code to split the file into a first part and a second part;

code to encrypt the first part and the second part;

code to upload the encrypted first part to a first cloud storage solution; and

code to upload the encrypted second part to a second cloud storage solution.

9. The computer program of claim 8, in which the first cloud storage solution is different from the second cloud storage solution.

10. The computer program of claim 8, in which the medium further comprises:

code to receive a request for the file;

code to retrieve the first part from the first cloud storage solution;

code to retrieve the second part from the second cloud storage solution; and

code to transmit the first part and the second part in response to the request.

11. The computer program of claim 10, in which the medium further comprises:

code to combine the first part and the second part; and

code to encrypt the combined first and second part before the step of transmitting the first part and the second part.

12. The computer program of claim 10, in which the medium further comprises:

code to receive an update for the file; and

code to update the first part and the second part corresponding to the update.

13. The computer program of claim 10, in which the medium further comprises:

code to receive metadata related to the file; and

code to store the metadata in a database server.

14. An apparatus, comprising:

a memory; and

a processor coupled to the memory, in which the processor is configured;

to receive a file for remote storage;

to split the file into a first part and a second part;

to encrypt the first part and the second part;

to upload the encrypted first part to a first cloud storage solution; and

to upload the encrypted second part to a second cloud storage solution.

15. The apparatus of claim 14, in which the first cloud storage solution is different from the second cloud storage solution.

16. The apparatus of claim 14, in which the processor is further configure to:

to receive a request for the file;

to retrieve the first part from the first cloud storage solution;

to retrieve the second part from the second cloud storage solution; and

to transmit the first part and the second part in response to the request.

17. The apparatus of claim 16, in which the processor is further configured:

to combine the first part and the second part; and

to encrypt the combined first and second part before the step of transmitting the first part and the second part.

18. The apparatus of claim 16, in which the processor is further configured:

to receive an update for the file; and

to update the first part and the second part corresponding to the update.

19. The apparatus of claim 16, in which the processor is further configured:

to receive metadata related to the file; and

to store the metadata in a database server.

20. The apparatus of claim 14, in which the file is received from a mobile app on a mobile device.
