chatbot-img GPT-4o - Answer
A resource-based policy explicitly preventing the deletion of the S3 bucket is indeed a robust approach. This policy can be set to specifically deny delete operations, thus safeguarding the backup files from accidental or unintended deletions. Such a comprehensive block on deletion ensures that the backups are preserved intact for the intended three-month period necessary for test and analysis purposes in the pre-production SAP system. This method is direct and less complex compared to other solutions that might require additional configurations or could still allow deletions under certain conditions.

chatbot-img GPT-4o - Answer
The correct choices C and D provide robust solutions for high availability and disaster recovery through the use of SAP HANA system replication and Amazon S3. For high availability, synchronizing data across different Availability Zones within the same region (eu-central-1) ensures minimal latency and no data loss. For disaster recovery, asynchronous replication is appropriate for another region (eu-west-1) due to higher latency considerations. Additionally, storing daily backups in S3 with Cross-Region Replication offers a solid DR plan by mitigating risks of regional disruptions. The usage of SYNC in high availability and ASYNC in DR strategies aligns with best practices for SAP HANA on AWS.
