Increasing the capacity speed and cost-effectiveness of data storage is a perpetual challenge. One of the most expensive and resource intensive tasks is gathering storing and protecting data backups. Writing data to tape and shipping and storing the tapes off-site is one of the largest financial and labor resource challenges in the conventional tape centric environment. The diagram illustrates the conventional process of handling backups through backup servers which then store that content in tape libraries. The tapes may be retained on-site for quick retrieval or in some cases shipped and stored off-site and data recovery must reverse the steps with an involved manual process of moving the data back on site.
Data Domain systems simplify the storage and handling of data by reducing, or in many cases entirely eliminating, the need for tape for data storage.
With Data Domain systems, data is backed up to disk instead of to tape. Data domain deduplication greatly reduces the data footprint before the data is backed up. Data domain global compression technology combines an exceptionally efficient high-performance in-line deduplication technology with a local compression technique. The reduced data footprint allows data to be retained on-site for longer periods and allows transfer across the network for archival. Data recovery is similarly transformed by the elimination of the time-consuming and resource intensive handling of tape.

This illustration provides a quick snapshot of the evolution of backup and recovery from tape to disk. From top to bottom, the conventional tape centric backup and recovery process has evolved from a heavily burdened manual process to some degree of automation with the introduction of VTL or virtual tape library systems.
More recently, the introduction of disk-based technologies such as Data Domain systems have transformed the process, providing both hybrid digital emulation of virtual tape library systems, as well as purely disk-based backup recovery and archival solutions.
Moving from left to right in the diagram, the move from tape to disk has had a significant effect on each important stage of the process including seamless integration with a wide variety of application backup clients and media management architectures. The move also provides a smaller footprint in the on-site backup storage space, and fast and efficient disaster recovery involving a process known as replication. With replication, disk-based backup data is replicated or copied off-premise to the disaster recovery site also known as the DR site. A number of additional Data Domain technologies provide a unique level of protection at the DR site.

For archiving and compliance solutions, Data Domain systems allow customers to cost-effectively archive non-changing data while keeping it online for fast reliable access and recovery.
These capabilities free up expensive storage to significantly improve operational efficiency and control costs. Data Domain provides a capacity optimized storage tier for backup and archive of data in a single system. File level retention locking enables active archive protection for IT governance. Data Domain systems offer field proven and automated data replication, data deduplication, enterprise management, and built-in data safety for extended on-site and off-site retention and recovery.
In combination, these capabilities enhance compliance and eDiscovery, allowing customers to adhere to government industry corporate and legal mandates
