overwriteMode property
A value that determines whether files at the destination should be
overwritten or preserved when copying files. If set to NEVER a
destination file will not be replaced by a source file, even if the
destination file differs from the source file. If you modify files in the
destination and you sync the files, you can use this value to protect
against overwriting those changes.
Some storage classes have specific behaviors that can affect your S3 storage cost. For detailed information, see using-storage-classes in the AWS DataSync User Guide.
