Step 4: Sync Files from Existing File Systems to Amazon EFS Using EFS File Sync

Now that you have created a functioning Amazon EFS file system, you can use EFS File Sync to sync files from an existing file system to Amazon EFS. EFS File Sync can sync your file data, and file system metadata such as ownership, time stamps, and access permissions.

In this step, we assume that you have the following:

  • A source NFS file system that you can sync from. This source system needs to be accessible over NFS version 3 or version 4. The source file system can be on-premises or on Amazon EC2.

  • A destination Amazon EFS file system to sync to. If you don't have an Amazon EFS file system, create one. For more information, see Getting Started with Amazon Elastic File System.

To get started with EFS File Sync, do the following:

  1. On the Amazon EFS Management Console, download and deploy a sync agent. For on-premises deployment the sync agent is provided as virtual machine (VM) image for VMware ESXi. For in the cloud deployment, you can create an Amazon EC2 instance from the community AMI.

  2. Create a sync task and configure your source and destination file systems.

  3. Start your sync task to begin syncing files from the source file system to the Amazon EFS file system.

  4. Monitor your sync task on the Amazon EFS console or from Amazon CloudWatch. For more information, see Monitoring EFS File Sync with Amazon CloudWatch.
