PI Archive Subsystem

The core PI Server component responsible for writing data to, reading data from, and otherwise managing the complete Data Archive. The PI Archive Subsystem is tightly coupled with the PI Snapshot Subsystem, which is responsible for performing compression on the incoming data. The PI Archive Subsystem is the historical record of time-series data maintained by PI Server. This term may be used to refer to the entire logical data record itself, a specific archive file, or the subsystem responsible for actively hosting the historical data record.
