NEW - AutoImport is on. Amazon FSx automatically imports directory listings of any new objects added to the linked S3 bucket that do not currently exist in the FSx file system.
NEW_CHANGED - AutoImport is on. Amazon FSx automatically imports file and directory listings of any new objects added to the S3 bucket and any existing objects that are changed in the S3 bucket after you choose this option.
NEW_CHANGED_DELETED - AutoImport is on. Amazon FSx automatically imports file and directory listings of any new objects added to the S3 bucket, any existing objects that are changed in the S3 bucket, and any objects that were deleted in the S3 bucket.
