The challenges with traditional VTL's include disk costs are too expensive for long-term retention. Backup data is too large to replicate over the WAN to a DR site. They still require of creating physical tapes to support post backup operations.
To summarize the benefits of Data Domain VTL, it starts with economics. There is less disk to resource and less to manage. The CPU-centric deduplication approach of SISL allows the system to be simpler to manage, as well as easier to provision.
In addition, Data Domain is more mature and flexible than most of its competitors. Finally, because of their resilience and replication flexibility Data Domain systems are highly reliable when deployed for VTL environments.

Data Domain systems support backups over the SAN and LAN. The backup application manages all data movement to and from Data Domain systems. The backup application manages physical tape creation. Data Domain replicator software manages virtual tape replication, and Data Domain System Manager is used to configure and manage tape emulations.
DD OS includes an NDMP tape server feature that simplifies the deployment of Data Domain systems for network attached storage or NAS devices. The feature is ideal to provide data protection for NAS systems and data centers or remote offices that use an Ethernet infrastructure, and complements the existing VTL over Fibre Channel capability.
The capability is included with purchase of the VTL software option, bundled with Fibre Channel HBA's, and is available to the VTL installed base.
