Compared with AWS tools
What each AWS tool does better, and where Douklar differs. Documentation comparisons, no benchmarks.
Douklar and native ECR and S3 replication
Replication keeps a destination current with every new push or write; Douklar moves what already exists, once.
Douklar and AWS Backup
AWS Backup keeps restorable copies inside one Organization; Douklar moves selected data between accounts that may not share one.
Douklar and DataSync and S3 Batch Operations
DataSync and S3 Batch Operations move very large amounts of storage; Douklar joins S3 with images, repositories and items in one run.
