 Cyber security has become an increasingly critical topic as malware and ransomware attacks continue to occur around the world. For mission-critical databases, such attacks leading to lost data and system downtime can have far-ranging impacts throughout the business in terms of revenue, operations, reputation, and even penalties.
 
-The purpose of Oracle Cloud Database Backup Service is to provide a secure, reliable, and cost-effective way to backup and recover Oracle Database workloads that are running in the cloud or on-premises. With this service, you can create backups of your databases and store them in Oracle Cloud Infrastructure Object Storage, which provides highly durable and scalable object storage.

 The service offers several benefits, including automated backups, point-in-time recovery, and backup retention policies. It enables you to quickly recover your data in case of data loss or corruption, and can also be used to migrate your databases to the cloud. Additionally, the service helps you meet your regulatory and compliance requirements by providing data encryption and secure backups.

 The following is an example run of the installer. This example shows how the installer automatically downloads the Oracle Database Cloud Backup Module for OCI for your operating system, creates a wallet that contains Oracle Database Backup Cloud Service identifiers and credentials, creates the backup module configuration file, and downloads the library necessary for backups and restores to Oracle Cloud Infrastructure.

 After installing the backup module, you'll configure the settings that will be used for backup and recovery operations. When using Recovery Manager (RMAN) for backup and recovery operations with Oracle Database Backup Cloud Service, you must configure your RMAN environment.

 To perform targetless duplication in RMAN without connecting to the source database or catalog, the BACKUP LOCATION clause is used. However, this method is only applicable when the source database backups are stored in a DISK location. If the source database utilizes Oracle Database Backup Cloud Service (e.g., ZDM or EBS Cloud Manager) for cloud backups, the following steps need to be followed:

 #### Validation/Testing
 
-Test Scenario – This script, named validation.sql, runs the validation queries while connected as sysdba. It provides a comprehensive validation report for the target database after the restore process. The script sets various SQL*Plus settings to control output formatting and executes the necessary queries. The results include information such as the PDB name, current date, database name, open mode, database status, logins, and status of distinct datafiles, tablespaces, tempfiles, and datafiles. It also reports the number of invalid objects and the count of recoverable files.
