Traditionally, data backup and disaster recovery were related but separate tasks. Backup tools were not integrated with storage system replication, so these tasks required separate management.
Today, this is increasingly not the case. Many backup software products have been integrated with storage system replication, so users can manage backup and DR from a single platform. Others offer native, software-based replication. Also, advancements in cloud backup and disaster recovery as a service (DRaaS) technologies have made cloud DR feasible for business use. Still many shops struggle with data backup and disaster recovery. If you count your organization among that group, this e-book chapter can help.
