Techniques for assessing data reduction efficiency

摘要

Techniques for determining data reduction options may include: receiving data reduction statistics for a data set including a first value of a first statistic denoting an amount of data reduction obtained for the data set when compression is enabled, a second value of a second statistic denoting an amount of data reduction obtained for the data set when deduplication is enabled, and a third value of a third statistic denoting an overlap in data reduction contribution when both compression and deduplication are enabled; and determining, in accordance with the data reduction statistics, a first setting denoting a current data reduction option enabled for the data set. A Venn diagram provided on a user interface display may illustrate data reduction benefits for the data set based on the data reduction statistics. Data reduction benefits for the data set may be reassessed to determine whether to modify the current data reduction option.
