A company is storing 700 terabytes of data on a large network-attached storage (NAS) system in its corporate data center. The company has a hybrid environment with a 10 Gbps AWS Direct Connect connection. After an audit from a regulator, the company has 90 days to move the data to the cloud. The company needs to move the data efficiently and without disruption. The company still needs to be able to access and update the data during the transfer window. Which solution will meet these requirements?

A
Create an AWS DataSync agent in the corporate data center. Create a data transfer task Start the transfer to an Amazon S3 bucket.
B
Back up the data to AWS Snowball Edge Storage Optimized devices. Ship the devices to an AWS data center. Mount a target Amazon S3 bucket on the on-premises file system.
C
Use rsync to copy the data directly from local storage to a designated Amazon S3 bucket over the Direct Connect connection.
D
Back up the data on tapes. Ship the tapes to an AWS data center. Mount a target Amazon S3 bucket on the on-premises file system.

Explanation
AWS DataSync (Option A) is the correct solution for several reasons:
-
Efficient large-scale data transfer: DataSync is specifically designed for moving large amounts of data between on-premises storage and AWS services. It can handle 700TB efficiently.
-
Incremental transfer capability: DataSync can perform incremental transfers, meaning only changed data is transferred after the initial sync. This allows the company to continue accessing and updating data during the 90-day transfer window.
-
Network optimization: DataSync optimizes network usage and can resume interrupted transfers, making it reliable for large data migrations.
-
No disruption: Since DataSync can perform incremental transfers, business operations can continue normally while data is being migrated.
Why other options are incorrect:
-
Option B (Snowball Edge): While Snowball Edge can handle large data transfers, it requires physical shipping and doesn't allow continuous access/updates during the 90-day window. The data would need to be frozen during the transfer process.
-
Option C (rsync): Rsync over Direct Connect would be inefficient for 700TB and wouldn't handle incremental updates well at this scale. It also lacks the optimization and monitoring capabilities of DataSync.
-
Option D (Tapes): This is outdated technology that doesn't support the requirement to access and update data during the transfer window. Tape backups would require freezing the data.
Key requirements satisfied by DataSync:
- ✅ 700TB data volume - Designed for petabyte-scale transfers
- ✅ 90-day timeline - Can complete within timeframe with incremental transfers
- ✅ No disruption - Incremental transfers allow continued access
- ✅ Access/update during transfer - DataSync tracks changes and syncs only what's modified
- ✅ Efficient transfer - Optimized protocol and network usage
- ✅ Direct Connect integration - Can leverage the existing 10 Gbps connection
DataSync provides the automated, incremental, and efficient data transfer needed for this hybrid cloud migration scenario while maintaining business continuity.
