しばしばDRと略される災害復旧のテクノロジは進歩しているが、一般的な課題も残っている。本リサーチノートでは、ビジネスとの連携、戦略、文書化、演習など、Gartnerが特定した問題のある20の領域に関して、I&Oリーダーが改善を試みる上で役立つヒントを紹介する。
多くの企業は、自社の災害復旧 (ディザスタ・リカバリ：DR) プランニングと、ビジネスに基づく要件や具体的な成果を整合させるのに苦心している。
DRプランニングの全側面を文書化する際に、詳細事項を最小限しか含めていない、またはそもそも記載していないのに加え、情報へのアクセスを適切に一元管理できていないことから、DRプランニングの実施が不首尾に終わっている。
インフラストラクチャ／オペレーション (I&O) のリーダーは、DRプランニングの演習が不十分または限定的であるために、必要とされる目標復旧時間 (RTO) でオペレーションを最も効果的に復旧させ復元する方法を理解できていない。
具体的なイベント・トリガーにフォーカスするのではなく、対象範囲を明確化し、損失のカテゴリに合った計画を立てることで、DRプランニングと事業継続管理 (BCM) の整合性を確保する。
主要な手順、役割、責任、リカバリ戦略をすべて洗い出し、DRプランニングの詳細事項を一元的に保管してアクセスしやすくすることで、DRプログラムの文書化を改善する。
DR演習を実施し、最新のビジネス・インパクト分析 (BIA) 結果と照合してリカバリ戦略を見直し、能力と範囲を拡大する機会を定期的に評価する。
