File system protection
When you create an Amazon EFS file system, its replication overwrite protection is enabled by default. Replication overwrite protection prevents file system from being used as the destination in a replication configuration. Before you can use the file system as the destination in a replication configuration, you must disable the protection. If you delete the replication configuration, the file system's replication overwrite protection is re-enabled and the file system becomes writeable.
Disabling replication overwrite protection requires permissions for the
elasticfilesystem:UpdateFileSystemProtection action. For more information, see
Amazon managed policy: AmazonElasticFileSystemFullAccess.
The status of the replication overwrite protection for an Amazon EFS file system can have one of the values described in the following table.
| File system state | Description |
|---|---|
| ENABLED | The file system cannot be used as the destination file system in a replication
configuration. The file system is writeable. Replication overwrite protection is
ENABLED by default. |
| DISABLED | The file system can be used as the destination file system in a replication configuration. |
| REPLICATING | The file system is being used as the destination file system in a replication configuration. The file system is read-only and is only modified only by Amazon EFS during replication. |
