Question

A media company is migrating 40 TB of files from an on-premises NFS file server to Amazon EFS as part of a data center consolidation. The migration must complete over an existing 1 Gbps Direct Connect link within a weekend, preserve file metadata and permissions, and automatically verify data integrity after transfer. The team wants to minimize custom scripting and operational effort. Which solution best meets these requirements?

Accepted Answer

Deploy an AWS DataSync agent on-premises and configure a task that transfers data from the NFS source to the EFS file system over the Direct Connect link.

Answer

Order an AWS Snowball Edge device, copy the files locally, and ship it to AWS to import the data into EFS.

Answer

Write a cron job using rsync on an EC2 instance to pull the files from the NFS server over the Direct Connect link into a mounted EFS file system.

Answer

Use AWS Storage Gateway in file mode to expose an S3 bucket, copy the files to it, then run an S3-to-EFS copy job.
