The HP StorageWorks D2D4000 Backup System provides automated, consolidated disk-based data protection for up to 16 servers in an intelligent self-managing 2U rack-mountable device, and the highest capacity and performance in the HP D2D Backup System Family. The D2D4000 Backup System boosts performance and reduces the backup window for small and medium sized data centers.The HP StorageWorks D2D4000 also features Dynamic reduplication which over a period of time cleverly removes redundant data to reduce the amount of backup capacity required on disk, resulting in up to 50x more backup data retained in the same raw disk. This cost-effective approach allows you to store more data on disk for longer, providing access to an increased number of available 'recovery points' and faster restore of lost or corrupted files.Seamlessly integrating into your existing Windows or Linux environment, the D2D4000 Backup System works with your software applications to automate the simultaneous daily backup of up to 16 servers into a single network-connected solution. Not only are there fewer devices to manage but reduced media handling also results in fewer errors and hardware-based RAID 6 further enhances reliability and lowers the risk of disk-based failure. Additionally the intuitive, web-browser based management interface lets you monitor your backup device from remote locations at any time.While the D2D4000 Backup System is ideal for daily backup jobs, regular offload to tape is still recommended as part of a disk-to-disk-to-tape solution combining the high data availability of disk with cost-effective long-term archival and offsite disaster recovery using tape. An easy-to-use tape offload feature allows you to copy or export cartridges from the system to a physical tape without affecting the performance of the network.
