Abstract
Systems and methods for performing data duplication on data that was previously consolidated (e.g., deduplicated or merged). An example method may comprise: receiving, by a processing device, a request to modify a storage block comprising data encrypted using a location dependent cryptographic input; causing the data of the storage block to be encrypted using a location independent cryptographic input corresponding to a first storage location; copying the data encrypted using the location independent cryptographic input from the first storage location to a second storage location; causing data at the second storage location to be encrypted using a location dependent cryptographic input corresponding to the second storage location; and updating a reference of the storage block from the first storage location to the second storage location.
