Right, “research potential options” is usually part of Crysis Management, which should precede any application of the DR procedures.

But there’s a wide range for the scope of those procedures, they might go from switching to secondary servers to a full rebuild from data backups on tape. In some cases they might be the best option even if the system is easily recoverable (eg: if the DR procedure is faster than the recovery options).

Just the ‘figuring out what the hell is going on’ phase can take several hours, if you can get the DR system up in less than that it’s certainly a good idea to roll it out. And if it turns out that you can fix the main system with a couple of lines of code that’s great, but noone should be getting chastised for switching the DR system on to keep the business going while the main machines are borked.

Grândola is a good choice, though because of the political association it will never be a hit with the non-leftist crowd. Dunas or A minha casinha are probably more popular/neutral choices and, unlike Zeca’s song, no-one outside of Portugal has ever heard about them (Grândola is well-known amongst at least some niche circles in Spain, where it was first released/sung during the dictatorship).

OTOH I’m fairly sure that in 50 years few will remember Xutos and GNR, while Grândola will still be sung over the centennial celebrations (assuming we don’t fall back into a far-right dictatorship by then…)
