A method for performing data backups is disclosed. The therapeutic material can be demineralized bone powder, and the carrier can be a poloxamer such as poloxamer 407. The data channel is structured to receive a number of data transport devices therein. The grippers may be actuated by hydraulic or other power provided by the lifting machine. At the same time, a magnetic field is generated from the ferrite core to produce a high-frequency induction hardened layer having progressively spreading skirt regions extending from a position in the vicinity of a center in an axial direction of the oil hole toward openings in ends of the oil hole. Additional variations of the system include array of probes configured to minimize the energy required to produce the desired effect.
