Abstract: One aspect of the present invention includes retrieving and recovering data chunks from alternate data stores in a storage management system which utilizes deduplication. In one embodiment, deduplication information for data chunks of data objects is stored at a system-wide level to enable the transfer and access of data chunks stored among multiple storage pools. When a data object is accessed on a first storage pool that contains damaged or inaccessible data chunks, the undamaged and accessible chunks may be retrieved from the first storage pool, in addition to retrieving an undamaged copy of the damaged or inaccessible data chunks from alternate data storage pools. Thus, a complete data object can be retrieved or recovered with a combination of chunks from the first storage pool and other storage pools within the storage management system, without requiring the entire data object to be retrieved from a backup source.

Abstract: The present invention provides for a system and method for assuring integrity of deduplicated data objects stored within a storage system. A data object is copied to secondary storage media, and a digital signature such as a checksum is generated of the data object. Then, deduplication is performed upon the data object and the data object is split into chunks. The chunks are combined when the data object is subsequently accessed, and a signature is generated for the reassembled data object. The reassembled data object is provided if the newly generated signature is identical to the originally generated signature, and otherwise a backup copy of the data object is provided from secondary storage media.

Abstract: An apparatus and system are disclosed for a pool drain cover, the cover having a perforated ramp around its perimeter to which are attached a plurality of straight, horizontally disposed tubes, circumscribing channels with substantially continuous cross-sectional areas, each tube enclosing a channel extending the length of the tube of at least six inches. The cross-sectional area of the tubes is kept at a minimum and their number is increased by arranging the tubes in rows and columns or giving the tubes an elliptical cross-sectional area and arranging them in a single row, thereby reducing the tapering in the tubes. The cover may be segmented and may be of multiple shapes, including a circle.

Abstract: An apparatus, system, and method for quantifying energy usage and savings enables applying the savings to a financial transaction. Quantification includes estimating and/or monitoring usage of utilities by detectors, comparing the usage to a predetermined baseline value, and valuating an energy savings. Quantification relies on a comprehensive database to establish the baseline and to predict usage and savings. A portion of the savings may be applied to any of early repayment of a mortgage loan, investment in securities, and a request for a credit. The method and system standardizes values of energy units and/or monetary units, and quantifies savings. The method and system aids in qualifying the building project based on a concrete estimation of energy savings or a savings within a range. Thus, the method forms a bridge between green, other energy conserving, or sustainable technologies and the financial markets.
