+## Use case
 
 An Exadata Cloud@Customer customer with requirements to run applications on-premises for data residency and/or latency reasons will likely appreciate the consumption model of the Compute Cloud@Customer (C3).\
 If said customer also has database backup infrastructure limitations and require a consumption based backup/recovery solution, the C3 could potentially deliver resources for the ExaDB-C@C backups and recovery. This document does not discuss the merits of such solution, but will validate the technical feasibility.
