A company needs to migrate $80\text{ TB}$ of data from an on-premises SMB file share to Amazon S3. The company has a $1\text{ Gbps}$ internet connection, but production traffic limits the available bandwidth for the migration to $50\text{ Mbps}$ . The migration must be completed within $10\text{ days}$ while minimizing overall transfer time. Once the bulk data is migrated, the company wants to continuously sync daily incremental changes over the network. Which two actions should the company take to meet these requirements?

Order an AWS Snowball Edge Storage Optimized device to perform the initial bulk data transfer.Answer
Deploy an AWS DataSync agent on-premises to sync incremental updates over the network after the bulk data is imported.Answer
C
Use AWS DataSync to copy the entire dataset directly over the available network connection within the 10-day window.
D
Set up AWS Transfer for SFTP to perform the initial bulk data migration over the network.
E
Use an AWS Snowball Edge device configured with the default AWS-managed KMS key for Amazon S3 (aws/s3) to encrypt the bulk data.

Answer

The company should order an AWS Snowball Edge Storage Optimized device to perform the initial bulk data transfer, and deploy an AWS DataSync agent on-premises to sync incremental updates over the network.

The correct actions are ordering an AWS Snowball Edge Storage Optimized device and deploying an AWS DataSync agent. Transferring

80\text{ TB}

over a

50\text{ Mbps}

network connection would take around

148\text{ days}

, which is too slow for the

10\text{ days}

requirement. Shipping the data using a Snowball Edge Storage Optimized device solves the bulk migration constraint. AWS DataSync is then used to sync daily incremental changes over the network.

Step-by-Step Solution

Calculate the total transfer time over the network using the available bandwidth.

The time to transfer

80\text{ TB}

(

6.4 \times 10^{14}\text{ bits}

) at

50\text{ Mbps}

is approximately

1.28 \times 10^7\text{ seconds}

, which is roughly

148\text{ days}

This identifies whether the online transfer window of

10\text{ days}

can be met.

Select the physical migration method for bulk data.

An AWS Snowball Edge Storage Optimized device is chosen for bulk transfer.

Shipping the device takes only a few days, enabling completion of the

80\text{ TB}

bulk migration within the

10\text{ days}

window.

Select the method for continuous daily synchronization.

An AWS DataSync agent is deployed on-premises to sync incremental updates over the network.

DataSync is optimized for network transfers and handles daily incremental updates efficiently without exceeding the

50\text{ Mbps}

bandwidth limit.
