Abstract
Data file storage systems and methods that bind a local portable data storage device to remote data storage space with an emergent data file storage system. Data files and directory nodes are associated with data aspect pairs, each comprised of a series of interdependent blocks of characteristically high-entropy data. Blocks of data comprising a remote data aspect are transferred to remote data aspect storage locations. A single block of data comprising a local data aspect is transferred separately to the local portable data storage device. Neither a local data aspect nor a remote data aspect contains information about the corresponding data file or directory node.

A computer-implemented method of binding a local data storage device to remote data storage space with an emergent data file storage system manifest only within the union of local and remote data storage spaces concurrently accessible to an application executing on a host computer, said method comprising:
- dividing, by the application executing on the host computer, a data object into a first set of data elements, wherein the first set of data elements includes a first total number of elements including a terminal element;
- generating, by the application executing on the host computer, a second set of data elements by identifying a cyclic order for the first set of data elements, performing an addition modulo-2 logical operation between adjacent elements of the first set of data elements as identified from the cyclic order, whereby each one of the second set of data elements results from a respective addition modulo-2 logical operation performed on a respective set of the adjacent elements of the first set of data elements as arranged in the cyclic order such that after all addition modulo-2 operations are performed a second total number of elements in the second set of data elements is less than the first total number of elements;
- transferring, by the application executing on the host computer, a local data aspect to the local portable data storage device;
- and
- transferring, by the application executing on the host computer, the second set of data elements to the remote data storage space.

A computer-implemented method of generating a data object, said generating comprising:
- retrieving from a local data storage device a local data aspect corresponding to the data object;
- retrieving from remote data storage space a remote data aspect corresponding to the data object;

- beginning with the first respective element of the first set of data elements, successively performing the addition modulo-2 logical operation between a next member of the second set of data elements from the cyclic order and a respective element of the first set of data elements derived from an immediately preceding addition modulo-2 logical operation until each member of the second set of data elements has been subjected to the addition modulo-2 logical operation and each of the first set of data elements has been derived, wherein, after all addition modulo-2 operations are performed, a first total number of the first set of data elements is greater than a second total number of the second set of data elements;
- and
- assembling each element of the first set of data elements together into the data object such that the data object includes a single coherent block of data having content substantially identical to said first set of data elements.
