AWS Backup enhanced Amazon S3 backup copy operations for buckets with millions of objects and low change rates, achieving up to eight times faster copy speeds. This improvement eliminates the need to scan destination accounts or regions comprehensively, relying instead on event-based change tracking.
By recording object events as they happen, AWS Backup reduces processing time and accelerates cross-account and cross-region copying automatically for all applicable new backup jobs. This enhancement is available at no extra cost across all supporting AWS Regions, helping customers better manage backup performance and costs.
