Synchronizing a Backup on-premises Db2 Server with Amazon RDS for Db2

This article explains how to synchronize an on-premises Db2 server with Amazon RDS for Db2 using archive log replication to Amazon S3.

• Enable archive log copying from RDS for Db2 to Amazon S3 bucket
• Configure IAM permissions and roles for S3 integration
• Restore database backup on self-managed Db2 in roll-forward pending state
• Periodically download and apply archive logs to maintain synchronization
• Three-stage process: establish RDS database, transition applications, maintain continuous backup alignment
• Monitor archive log copy status and troubleshoot configuration errors
• Implement automated cron jobs for continuous log application
• Use online backups for compatibility with roll-forward operations

This hybrid approach enables organizations to maintain synchronized backup servers while leveraging managed RDS benefits, supporting migration, disaster recovery, and development scenarios.
