Secure distributed backup for personal device and cloud data

A storage device or storage disk comprising instructions which, when executed, cause a processor to at least:

• in response to a request for a file from a client device, obtain a map corresponding to the file from a remote device;
• request a first file chunk from a first cloud storage location based on the map, the map including (A) the first cloud storage location for the first file chunk on a first cloud storage service and (B) first login information to access the first cloud storage service;
• request a second file chunk from a second cloud storage location based on the map, the map including (A) the second cloud storage location for the second file chunk on a second cloud storage service and (B) second login information to access the second cloud storage service;
• generate the file by combining the first file chunk and the second file chunk;
• and
• cause transmission of the file to the client device.
