Felix shows you how to
set up an EFS File Sync
between two EFS systems


I want to keep two Amazon Elastic File System (EFS) file systems in sync. Or, I want to migrate my Amazon EFS file system for one or more of the following reasons:

  • To change from General Purpose to Max I/O performance mode
  • To use encryption
  • To move the file system to another AWS Region

How do I create an Amazon EFS File Sync between two EFS file systems to migrate or copy data between them?

EFS File Sync migrates your data and keeps it in sync until all data is moved over. For instructions on how to create an EFS File Sync between two EFS file systems, see Walkthrough 8: Sync a File System from Amazon EC2 to Amazon EFS Using EFS File Sync.

Warning: The workload and size of the source file system can affect the time it takes to sync, as well as the use of burst credits on the destination file system.
