backup, data compression, and data deduplication to reduce the backend storage footprint. It uses byte-level, variable block-based software deduplication and is hardware-agnostic, so no specialized drives or appliances are needed. NetVault Bare Metal Recovery enables users to restore a computer from its "bare metal" state—including the necessary operating system, network settings, system settings, applications, disk partitions, and data. NetApp options Quest supports NetApp products with the following technologies: SnapMirror to Tape – Working in conjunction with the NetApp’s SnapMirror technology, NetVault SnapMirror to Tape enables full volumes on filers to be mirrored and backed up to tape to provide the ability to store data offsite for disaster recovery. SnapVault Manager – SnapVault Manager provides a graphical interface that is integrated with NetVault Backup to provide a single point of enterprise-wide control of NetApp’s SnapVault. This allows organizations to back up changed data from multiple storage platforms to a common Snapshot target on NetApp appliances. Snapshot Manager – The NetVault NDMP Snapshot Manager allows organizations to generate, automatically schedule and recover snapshots through NetVault’s GUI. Disk targets Originally NetVault Backup was intended to back up to physical tapes in tape drives. However, the product was soon extended to support backup to disk. For data deduplication, NetVault Backup supports Quest's DR appliance and NetVault SmartDisk. The Dell DR appliance is a hardware-based, inline deduplication storage product. Its deduplication engine was originally developed by Ocarina Networks. The NetVault and Ocarina engineering teams worked to integrate the two technologies. NetVault Backup can also be used with NetVault SmartDisk, which is a disk storage repository and deduplication product. NetVault SmartDisk can perform post-process data deduplication. It represents a contiguous storage pool on disk without being subdivided into virtual tapes or slots for easier management and allows for byte-level, variable block-based software deduplication. NetVault Backup supports EMC Data Domain via DD Boost and Quantum DXi. For LAN-free backups, NetVault Backup can write to a physical tape drive or VTL that is shared between multiple machines using Fibre Channel or iSCSI. History 1989: The NetVault product was originally a product developed by AT&T for internal use. 1992: AT&T contracted UK company Willow Ltd to provide tape library support. At that time, NetVault Backup was at version 2.0. Willow Ltd added Tape Library management, a Graphical User Interface and heterogeneous platform support. 1996: AT&T spun off the NetVault product into a separate private company, CommVault, through a management
