1. A method of managing the storage of data in a computer network, the method comprising:

  • receiving data from a source system comprising computer hardware at a destination system comprising computer hardware including one or more processors, the data comprising at least one first stub file comprising information indicative of a location of additional data on a storage device;

    storing the data at a destination storage device included with the destination system, wherein the destination storage device differs from the storage device;

    identifying a first portion of the data for storage at a secondary storage device, wherein the secondary storage device differs from the storage device and the destination storage device;

    providing a copy of the first portion of the data for storage in the secondary storage device;

    generating a second stub file representative of the first portion of the data;

    replacing the first portion of the data at the destination storage device with the second stub file; and

    tagging the second stub file with an identifier that distinguishes stub files generated at the destination system from stub files received with the data from the source system, wherein the second stub file comprises information indicative of a location of the copy of the first portion of the data on the secondary storage device, and wherein the at least one first stub file is not tagged with the identifier.
