Abstract: The Back Up Data Across Cloud Trust Zone Apparatuses, Processes and Systems (“BUDACTZ”) transforms resource backup registration input, resource backup execution request, resource restore input datastructure/inputs via BUDACTZ components into resource backup registration output, resource backup execution response, resource restore output outputs. A resource backup registration datastructure structured to specify a partner shared cloud protected zone is obtained. A partner zone administrator authorization token datastructure is obtained. A partner zone service account for the partner shared cloud protected zone is created using the partner zone administrator authorization token datastructure. A partner zone resource to be serviced is determined. A shared cloud backup zone is determined. A backup resource for the partner zone resource is created in the shared cloud backup zone. A service agent installation token datastructure structured to associate the partner zone resource and the backup resource is generated.
