Consolidating encrypted image backups without decryption. In one example embodiment, a method for consolidating encrypted image backups without decryption may include individually encrypting, using a single encryption function, each block in a first set of blocks in a source storage, storing the first set of encrypted blocks in a first encrypted image backup, individually encrypting, using the single encryption function, each block in a second set of blocks in the source storage, storing the second set of encrypted blocks in a second encrypted image backup, and creating a consolidated encrypted image backup that includes a single encrypted block for each of multiple unique block positions represented by the first and second sets of encrypted blocks without decrypting any of the encrypted blocks.
