AWS Backup Audit Manager
Incremental backup

Full AWS Backup management
Item-level restore

Destination copies from S3 buckets and RDS databases with PITR are not Point-in-Time restorable (PITR).

Cross-account and cross-Region copies are available for S3 backups, but copies of continuous backups do not have point-in-time restore capabilities.

這句我看不懂

For both backup types, the first backup is a full backup, while subsequent backups are incremental at object-level. For example, if there is a 1 kB change in your 1 GB object, the subsequent backup will create a new 1 GB object in the backup vault.
