libraries, the secondary mount path must be a unique location.
Conclusion
DDR Remote Single Instance Backup capability provides an efficient and effective option to protect
remote offices by providing local backup and restore capabilities along with a secondary disaster recovery
copy at a central site. By combining a Replicated Disk Library and Single Instancing, DDR provides the
ability to create secondary disaster recovery copies while achieving maximum network efficiencies.
Available enterprise-class features—like data encryption and compression—provide additional tools to
implement a secure, robust, and optimal remote office protection strategy.
