Abstract: An exemplary system preserves the autonomy of two or more distinct storage management systems all the while enabling backed up data to be restored from a first storage management system (the “local system”) to a specially-configured client in a second storage management system (the “remote system”). For example, backed up data in the local system (e.g., a secondary copy of production data) may be transferred, in a restore operation, from secondary storage in the local storage management system, which originated the data, to a client of the remote storage management system (the “remote client”). As a specially-configured “restore-only client,” the remote client is limited to receiving backed up data from the local storage management system, via restore operation(s) managed by the local storage manager. The remote client remains a full-fledged client in its home system, the remote storage management system.
