DataSync moves large amounts of file data between on-premises storage and AWS (or between AWS storage services) quickly and automatically, handling encryption, verification, and scheduling.
DataSync vs DMS vs Snowball
DataSync = online file/object transfer over the network, great for ongoing or large one-time file migrations to S3, EFS, or FSx. DMS = database migration. Snowball = physical device for huge transfers when the network is too slow. Scenario about moving file shares or NFS/SMB data to AWS over the network? DataSync.
