Rampant data growth makes slaves of us all. The effects are well known: massive growth in storage infrastructure, prematurely obsolete storage resources, the endless scramble to stay on top of it all.
Storage vendors have reacted to the onslaught with cheaper, more capable primary storage hardware to sate the data addiction. But as primary storage resources are continuously upgraded in response to growth, disaster recovery and business continuity architectures are often pushed beyond their original design limits -- leaving organizations at significant risk.
A failure to plan is a plan for failure
The dangers of neglecting to plan expansion of BC/DR capabilities in lockstep with those of the primary storage environment are many and varied. The most common examples I've seen can be found in traditional backup infrastructures.
All too often, so much primary data needs to be supported that backup windows start overlapping with production hours. To prevent that encroachment, well-meaning admins often start by trimming "unimportant" data out of the backup rotation. But it usually doesn't end there. Before long, entire servers are being backed up less frequently, then sometimes not at all. From there, you're only a hop, skip, and a jump from neglecting to protect something that is important and living to regret it.
