	The TANGO release 8 led to several enhancements, including the adoption of the ZeroMQ library for faster and lightweight event-driven communication. Exploiting these improved capabilities, a high performance, event-driven archiving system written in C++ has been developed. It inherits the database structure from the existing TANGO Historical Data Base (HDB) and introduces new storage architecture possibilities, better internal diagnostic capabilities and an optimized API. Its design allows storing data into traditional database management systems such as MySQL or into NoSQL database such as Apache Cassandra. This paper describes the software design of the new HDB++ archiving system, the current state of the implementation and gives some performance figures and use cases.

	The TANGO archiving system HDB++ continuously stores data over time into the historical database. The new time-machine application, a specialization of the extensively used save/restore framework, allows bringing back sets of control system variables to their values at a precise date and time in the past. Given the desired time stamp t0 and a set of TANGO attributes, the values recorded at the most recent date and time preceding or equaling t0 are fetched from the historical database. The user can examine the list of variables with their values before performing a full or partial restoration of the set. The time-machine seamlessly integrates with the well known save/restore application, sharing many of its characteristics and functionalities, such as the matrix-based subset selection, the live difference view and the simple and effective user interface.
