Chernobyl took out a couple of datacenters, so 35 years DR is the current record :) DR contract duration is a pricing decision, most can be extended indefinitely but get very expensive (and they have a "cause majeure" clause which allows DR site to dump you under some circumstances). Typical contracts are for 30 and 90 days, some cultural variation by country. It comes down to cost and a bigger factor is often the DR test terms.
