Abstract
Embodiments are directed to techniques for matching the storage tiers used to back a cloned storage object with the storage tiers used to back the source storage object from which the cloned storage object is to be created. This may be done by determining the storage tier for each source storage extent that backs the source storage object and allocating, for each source storage extent, a corresponding cloned storage extent that matches that source storage extent. Data may then be copied from each storage extent on the source to the corresponding storage extent on the clone.
