Transparent adaptive file transform

Embodiments of methods, systems, and services for transparent adaptive file transform are described. In one embodiment a method for transparent adaptive file transform is performed by a data processing device. The method may include automatically detecting a data transfer addressed to an external data storage. The method may also include redirecting data associated with the data transfer to a data transformer. Additionally, the method may include applying one or more data transforms to the data associated with the data transfer to generate a transformed data set. In an embodiment, the method may also include transferring the transformed data set to the external data storage. In one embodiment, the external data storage is a cloud storage facility.
