Abstract:
1. A computer-implemented method, comprising: receiving a request to evaluate deduplication effectiveness of a deduplicated storage system; examining, in response to the request, metadata of first data chunks associated with the deduplicated storage system, the first data chunks being partitioned from one or more data files according to a first chunk size; calculating a plurality of new chunk sizes based on the examination of the metadata of first data chunks; merging metadata of the first data chunks according to each of the plurality of new chunk sizes to represent new data chunks to which the first data chunks would have been merged; determining a deduplication rate of each of the new data chunks based on the merged metadata; and selecting a second chunk size from the plurality of new chunk sizes, wherein the second chunk size has the highest deduplication rate among all the plurality of new chunk sizes.
