Described are systems and methods for storing a variable number of instances of data objects (e.g., 1, 2, 3, or up to N−1 instances, where N is the number of instances of the data object included in primary data) in secondary storage across a data storage network. In some examples, a system for storing a variable number of instances of data objects includes, one or more computing devices storing a set of data objects and multiple storage devices distinct from the one or more computing devices. Each of the multiple storage devices is configured to store at least a single instance of a data object. The system also includes a database configured to store information associated with the data objects. This information includes substantially unique identifiers for the data objects and, for each of the data objects, a number of instances of the data object stored on the multiple storage devices.
