Summary:Techniques for distributing data in a distributed data storage system using a hierarchy rule that is generated based on a spreading policy and a set of tolerable failures specified by a user in absence of system deployment information are disclosed. The system includes a controller node which receives a request including a spreading policy and a protection level for spreading a first data object. The controller node determines a hierarchy rule corresponding to the spreading policy based on the protection level. The controller node distributes the first data object in the system using the hierarchy rule and the spreading policy. The controller node receives a reconfiguration of system deployment. The controller node distributes a second data object in the system based on providing protection of the protection level to the second data object without affecting protection of the same protection level applied to the first data object.
