Having processes for data-backup and data-recovery helps your enterprise maintain business continuity since (should the worst happen and your data is lost) the data can be restored from a backup. In some locales a backup and recovery process that meets a set minimum requirements is something that a business must have in order to comply with local law.
Today, enterprises the world over clearly understand that company data is very important and not just for business continuity, but for the very continued existence of the enterprise itself. Protecting data and ensuring that it is accessible around the clock is a critical task and therefore it is important that it be executed well.
One of the most recent and important operational challenges is the sheer variety of solutions available—each one a good solution if deployed in the right place. Many enterprises qualify for one of more of these solutions, so with such a diversity of choices you will often see many, different data protection schemes running in the same organization.
