White Paper: Disk Based Data Protection With NetVault: Backup And Data Domain

With the cost of hard disk storage decreasing and data volume capacities increasing, a large number of companies are integrating hard disks as a storage element in their backup and recovery solutions. Disk to disk backup provides enhanced performance and reliability, and when used in conjunction with tape-based backup, provides a comprehensive data protection capability.

Disk drives offer direct random access, enabling multiple concurrent backup sessions and read/write efficiency improvements. The resulting productivity gains and lowered operating expense lead to significant time and cost savings. In comparison, tape technology, which uses sequential access, is much slower. Still, tape plays a vital role in backup and recovery operations, especially with longer term data retention and archival.

NetVault: Backup delivers a number of best-of-class, disk-to-disk data protection solutions that include a virtual tape library (VTL). Operating exactly like an actual tape library, NetVault: Backup VTL offers similar advantages of tape with the additional merits of disk's high-speed access and low cost. The integrated tape library emulation on disk VTL is a standard feature of NetVault: Backup.
