A customer wants to upgrade to a backup solution that provides fast restores with longer data retention times and easy integration. Which backup solution meets their requirements?

Remote replication is designed for disaster recovery and continuous data availability, not for optimizing backup restore speed or managing long-term retention within a backup catalog.

Application-based disk backup solutions can provide fast restores but typically lack the deduplication and scalable virtual tape emulation needed for cost-effective long data retention.

A NAS appliance is a general-purpose network storage device and does not natively provide the tape library emulation, deduplication, or integrated backup management features required for long retention and easy integration.

A virtual library system presents disk-based storage as virtual tape drives and cartridges, so backup applications can interface with it using existing tape workflows without reconfiguration. Because data resides on disk rather than physical tape, restores are significantly faster, and built-in deduplication enables longer retention within the same physical capacity.
