In this article we shall discuss creating an Oracle Database 18c cloud service instance from a backup. An Oracle Database 18c instance may be created on Oracle Database Cloud Service, as discussed in Using Toad for Oracle with Oracle Database 18c - Part I. A new Oracle Database 18c Cloud Service instance may also be created with database instantiation from cloud-based backup of an Oracle Database Cloud Service database or an on-premises Oracle database. The requirement is that the backup is in the cloud. Instantiating from backup is the process of creating a new Oracle Database Cloud Service instance and replacing its database with a cloud backup of another Oracle Database. The database from which the cloud backup is made is called the “source database”.
