Reserve Data System
From Army.ca Wiki
The Reserve Data System (RDS) was in place from 1976 through 1998, and contained pay and Human Resources information on members of the Reserve Force. Its pay functionality was replaced by RPSR, with the HR information replaced by HRMS.
Unfortunately, the Department of National Defence has not adequately maintained the data from RDS and it is questionable whether any data is still readable. Accorind to one source within DND, efforts to recover the data from old copies have been failed, and efforts are underway to identify another source of the data.
