Amazon FSx for NetApp ONTAP fully supports native NetApp SnapMirror replication, making it the most efficient and reliable option for migrating NetApp data from on-premises to AWS.
From AWS Documentation:
“You can use SnapMirror to replicate data from your on-premises NetApp systems to FSx for ONTAP for seamless, block-level, incremental transfers. This provides a highly efficient and performant method for migration, especially for large datasets.”
(Source: Amazon FSx for NetApp ONTAP – Migration Guide)
Why Option C is correct:
SnapMirror offers block-level replication, making it highly efficient for millions of small files.
It supports NFS and SMB file shares, preserving directory structures and permissions.
Reduces cutover time and allows for incremental syncs.
Uses the existing 10 Gbps network for fast transfers.
Why the other options are incorrect:
Option A (DataSync): Suitable for many file-based migrations but less efficient for very large datasets with millions of small files compared to SnapMirror.
Option B (Storage Gateway): Volume Gateway is not used for full-scale file migrations; it's for hybrid cloud access.
Option D (Snowball Edge): Useful for offline migrations, but online SnapMirror is more efficient and avoids shipping delays.
