A company needs to copy an Amazon Aurora database from one AWS account to a...

AWS Backup provides managed backup plans and supports cross-account and cross-Region backup copy workflows for supported AWS resources, including database backup scenarios. This is the least operationally intensive approach because scheduling, retention, copy operations, and monitoring are handled by AWS Backup instead of custom scripts. Option B can work but requires Lambda code, credentials, retries, error handling, and maintenance. Option C exports data to S3 and then replicates files, which is not the same as a managed Aurora backup copy and adds unnecessary complexity. AWS Application Migration Service is intended for server migration and lift-and-shift replication, not daily Aurora database backup copying. Therefore, an AWS Backup plan with the second account and second Region as the destination best matches automated disaster recovery and operational efficiency.
