Abstract
Embodiments of the present invention provide a system, method and computer program products for estimating data reduction in a file system. A method includes selecting a sample of all data from data files in the file system, wherein said sample represent a subset of all the data in the file system. The method further includes estimating a data reduction ratio by data deduplication for the file system based on said sample. The method further includes estimating a data reduction ratio by data compression for the file system based said sample. The method further includes generating a combined data reduction estimate for the file system based on said data compression estimate and said data deduplication estimate.
