1. A method comprising:
receiving, by a first storage system from a computing device, data to be stored on the first storage system;
generating, by the first storage system, reduced data from the data using one or more data reduction techniques including deduplicating the data against other data stored on the first storage system;
encrypting, by the first storage system, the reduced data using an encryption key that is different from an other encryption key used by the first storage system to encrypt the stored reduced data;
sending, from the first storage system to a second storage system, the reduced data encrypted with the encryption key that is different from the other encryption key used by the first storage system; and
recovering, from the second storage system, the reduced data, wherein the reduced data is encrypted with the encryption key that is different from the other encryption key used by the first storage system.
