200 TB of on-prem file data must move to S3 continuously over a 10 Gbps Direct Connect — ongoing sync during a phased migration, not a one-time bulk load. Which service?
A.Snowball Edge
Snowball is offline bulk — wrong for continuous sync.
B.AWS DataSync — online, incremental, scheduled transfers
Correct. Online incremental transfer over the link you have.
C.S3 Transfer Acceleration
TA accelerates S3 uploads — it's not a sync service.
D.Storage Gateway file shares only
File Gateway exposes SMB/NFS — not bulk migration machinery.
Why this answer
DataSync is the online transfer service — agents on-prem, scheduled incremental syncs over DX/VPN/internet, built-in validation. Snowball is for offline bulk when bandwidth is insufficient; 10 Gbps DX makes online transfer clearly correct for ongoing sync.
