Methods and systems for contiguous utilization of individual end-user-based cloud-storage subscriptions

A system for contiguous utilization of individual end-user-based cloud-storage subscriptions, the system comprising:

• (a) a CPU for performing computational operations;
• (b) a memory for storing data and having computer-readable code embodied therein, wherein said computer-readable code includes program code for a privacy gateway, configured for providing the contiguous utilization of cloud storage, having:
• (i) program code for a gateway receiver configured for receiving a write request for writing a data file into at least one cloud-storage allocation unit and storing said data file in a cache of said memory, wherein said at least one cloud-storage allocation unit is partitioned to include primary storage areas and secondary storage areas with each said storage area having unique read/write privileges;
• (ii) program code for storage mapping configured for identifying unused available storage in said at least one cloud-storage allocation unit;
• (iii) program code for file-chunking configured for fragmenting said data file into chunk files;
• (iv) program code for encryption configured for encrypting each said chunk file;
• (v) program code for a cloud writer configured for writing said each chunk file exclusively to portions of said secondary storage areas of said at least one cloud-storage allocation unit, based on said unique read/write privileges, to satisfy said write request;
• and
• (vi) program code for metadata-lookup configured for performing lookup and/or updating a metadatabase having metadata associated with said data file and said chunk files, said updating includes mapping said secondary storage areas and associating said unique read/write privileges with said mapping.

A non-transitory computer-readable storage medium, having computer-readable code embodied on the non-transitory computer-readable storage medium, for contiguous utilization of individual end-user-based cloud-storage subscriptions, the computer-readable code comprising:

• (a) program code for, upon receiving a write request for writing a data file into at least one cloud-storage allocation unit, identifying unused available storage in said at least one cloud-storage allocation unit, wherein said at least one cloud-storage allocation unit is partitioned to include primary storage areas and secondary storage areas with each said storage area having unique read/write privileges;
• (b) program code for fragmenting said data file into chunk files;
• (c) program code for encrypting each said chunk file;
• (d) program code for writing said each chunk file exclusively to portions of said secondary storage areas of said at least one cloud-storage allocation unit, based on said unique read/write privileges, to satisfy said write request;
• and
• (e) program code for updating a metadatabase having metadata associated with said data file and said chunk files, said updating includes mapping said secondary storage areas and associating said unique read/write privileges with said mapping.
