Archive Backup Chain

The forever forward incremental backup method is not implemented for DB instances — during every archive session Veeam Backup for AWS creates a full backup in the archive backup chain:

1. During the first archive session, Veeam Backup for AWS detects backed-up data that is stored in the backups existing in the regular backup chain, creates a full archive backup with all the data, and copies this backup to the archive repository. The full archive backup becomes a starting point in the archive chain.
2. During subsequent archive sessions, Veeam Backup for AWS continues to create full archive backups.

The period of time during which RDS backups are kept in the archive backup chain is defined by retention policy settings. For more information, see Retention Policy for Archived Backups.
