Abstract
Different management applications corresponding to different private computing systems that are untrusted with respect to each other reciprocally agree to store for each other replicated versions of logical volumes of storage arrays as backups. A management server corresponding to one or more storage arrays at a local one of the computing systems encrypts a volume to be backed up at the other remote computing system and transmits the encrypted version to the remote computing system. The remote computing system cannot modify or delete a portion of an array that has stored thereon the encrypted version of the logical volume without having a configuration-change key generated by the local management server, which may generate the configuration-change key to facilitate mirroring at the remote storage array a modification made to the local storage array.
