Hi, sorry, just get so used to acronyms so quickly 'round here,,,
BC = business continuity (e.g. when the Exchange server's power supply dies but your users still need access to their emails) usually a short-term measure until you can get up and running again
DRM (a.k.a. DRP) = Disaster Recovery Management/Plan (e.g. when the building burns down and you need both short term measures to keep trading as well as the ability to restore everything that was lost)
"I am still trying to figure out why ASG stopped emailing me with white/black list requests" - changed email address?
forest/desert/ice-cap/mid-Atlantic, he would still be wrong
