Disaster Recovery - doing it for real


Business/IT alignment, IT governance

What experience do you have of invoking your Disaster Recovery procedures for real? Like all good IT departments we have a procedure which is trialled each year. The true test, of course, only comes when you have to use it in anger.

Fortunately, I have no real life experience in disaster recovery. However, in more than half of the cases the regular checks / trials on the Recovery (or even restoring a back-up) show enough reason for worry: back-up that cannot be read anymore, upgraded restore SW that cannot read the older back-ups anymore, accidental erase of the back-up, incremental back-ups overwriting a full back-up.
If one makes sure things as listed here do not happen, I believe you may consider yourself already a good team leader.

I have had the experience of participating in a real disaster recovery process due to the 1994 Northridge earthquake in California. Fortunately, we had established and had somewhat rehearsed minimal but adequate disaster recovery procedures. Following the recovery, which involved moving the entire corporate headquarters due to structural damage to the HQ buildings, we thoroughly reviewed/revised/updated those procedures and brought in a professional DR/Hazmat consulting group to close the loop. The key element in my mind was the rehearsal(s) process which is always so difficult to sustain due to daily fire-fights.

Several years ago, with the train crash in Baltimore that cut the main fiber line, we had to switch to an alternate server based system, even though it was a “minimal” access capable system, it worked. We have redundant systems in place with a third system on a separate fiber and physical location that monitors both systems. This way no trials are necessary. The databases are kept in sync for our clients.
