DataDomain Virtual Tape Library
Back to product information
Traditional Virtual Tape Library (VTL) systems and disk backup systems can only provide a frontend, fast cache to a tape library infrastructure, temporarily alleviating backup window problems.
None can replace tape automation technology because they lack the requisite economic and operational qualities. These systems cannot cost efficiently retain backup data for any length of time, and backup data is too large to be vaulted over a Wide Area Network (WAN).
They do not offer an evolution from tape and its associated challenges and ironically, tape remains the primary method of retention, recoverability and disaster protection. Data Domain changes all that. Powered by Data Domain’s Global Compression™ technology for high-speed, inline data deduplication, backup data is reduced in size by 20x on average. This makes disk backup storage cost-effective for long-term on-site retention and highly efficient for vaulting data offsite for disaster recovery (DR). |
