This white paper focuses on four typical use cases for integrating the Dell DR4000 advanced disk backup and disaster recovery appliance into existing tape infrastructure. With its efficient deduplication and compression algorithms, the DR4000 can be a cost-effective and critical addition to an organization’s disaster recovery plans. The DR4000 usually replaces a tape drive or library as the primary backup solution because it can deliver fast full backups and restores more efficiently than traditional tape devices. Using a combination of the DR4000 for primary backups and existing tape infrastructure for secondary backups, it provides a high-performance and reliable solution to meet legal obligations or business requirements for off-site storage, archiving and disaster recovery. In addition, the recent release of the DR4000 Rapid Data Access software plug-in enables more efficient workflows such as automating disk-to-tape backups to consolidate tape backup systems from remote sites into the data center.
