Selecting a Disaster Recovery Center Location
When preparing a Disaster Recovery Center, one of the most important decisions is the location of the Disaster Recovery Center.
Up until 9/11, a lot of companies held their DR centers in the adjacent building, and right after 9/11, everyone wanted to go as far from the primary data center as possible.
One of the common misconceptions of Disaster Recovery planning is that longer distance ensures better disaster protection.
Of course, increasing the distance between data centers reduces the likelihood that the two centers are affected by the same disaster. But just putting distance between locations may not be sufficient protection.
In reality, the best distance for a DR location is dictated by a multitude of factors. There is no such thing as an ideal Disaster Recovery location. The optimal location is the one that minimizes the risks at an acceptable cost and meets the required SLAs and authorities’ regulations.
