The data protection level (DPL) for an object is the number of copies of the object HCP must maintain in the repository to ensure the integrity and availability of the object. Regardless of the DPL, you see each object as a single entity.
Each copy of the data for an object is stored on a different HCP node. For example, if an object has two copies (that is, it’s in a namespace with a DPL of two), its data is stored on two different nodes.
The DPL is determined by the namespace configuration. You can view the DPL for an object, but you cannot change it. However, namespace configuration changes can cause the DPL to change.
With HTTP, the data protection level for an object is returned by the X-HCP-DPL response header. With the WebDAV, CIFS, and NFS protocols, you view this value in the dpl.txt metafile.
