What are Atmos policies?
Atmos Policies define durability, availability and other data services attributes that will be assigned to an object or group of objects. The attributes currently include: number of copies, distribution of copies, compression of copies and location of copies to hard drives that spin down when they are not being accessed. Storage Policies are designated by the application. If you are a developer and are trying to apply policies, the Atmos Online User Guide will contain the necessary instructions.
