Abstract: A method for pricing data recovery for a sequence of time periods based on an estimate of the amount of data that will be recovered. For the first period, the price is the backup capacity times a price rate times an assumed recovery rate, which is a pre-determined number. For subsequent periods, the price is the backup capacity times the price rate times the actual amount of data recovered in the prior time period. The method also includes a data backup and recovery method using the data recovery pricing method, which provides tracker software to measure the amount of data recovered.

Abstract: An apparatus for cleaning out material which remains within a confined space, such as silos, hoppers and the like, is disclosed. The apparatus includes a power driven device for impacting the material which is hung up within the silo to loosen it and allow it to fall downwardly of the silo. The device for impacting the material is suspended from and powered by a cable/hose which is reeled onto a drum supported above the material in the silo. The drum is rotatable to payout or rewind the cable/hose in positioning the impacting device in the area of the material to be loosened. The apparatus includes provision for automatically reciprocating the impacting device along the material face and in the event of a material avalanche, releasing the drum to allow the impacting device to fall downwardly with the flowing material.
