The National Trades Union Congress (NTUC) is Singapore's largest a federation of trade unions, consisting of more than sixty unions, nine cooperatives, and six affiliated organizations. The IT department, which had not increased in team size, was responsible for 46 servers and more than 1,000 users from 29 organizations. The strain, as a result of the four-fold user increase, was considerable. To boot, NTUC's disaster-recovery setup needed improvement to shorten its recovery time.
