If a continuous backup rule also specifies a cross-account or cross-Region copy, AWS Backup takes a snapshot of the continuous backup and copies that snapshot to the destination vault. To learn more about copying your recovery points across accounts and Regions, see Copying a backup .
Continuous backups create a periodic backups in accordance with the frequency set in the backup plan rule in the destination account and/or Region.
AWS Backup does not support on-demand copies of continuous backups.
