Abstract
A method is used in managing data deduplication in storage systems based on storage space characteristics. Characteristics of first and second storage tiers are evaluated. A first data object resides on the first storage tier and a second data object resides on the second storage tier. The first and second data objects are selected for applying a deduplicating technique. A data storage system includes the first and second storage tiers configured such that performance characteristics associated with the first storage tier is different from the second storage tier. Based on the evaluation, the deduplicating technique is applied to the first and second data objects.
