Abstract: In one example, a method for facilitating read-write processes in a read-only environment includes intercepting a write request directed to read-only data, the write request including a data block. A file object construct is then created that is representative of the read-only data, and the file object construct is stored in association with a unique identifier. The data block of the write request is written to a data structure so that the data block is mapped to the file object construct. The file object construct, when retrieved, includes a representation of the read-only data modified in accordance with the write request, but no change is required to be made to the underlying read-only data.
