Making Use of Virtual Tape in a D2D2T Environment
Source: Clipper Group
A Virtual Tape Library enables a centralized, shared backup and recovery facility for the midsized data center. Combined with tape, in an integrated D2D2T environment, a VTL also becomes an integral component in an archival architecture. By connecting a VTL to a SAN, a single VTL appliance can serve as a backup/archival target for multiple heterogeneous servers throughout the data center or across a campus. One has a significant amount of scalability to work with, as he or she can configure VTL with as few as 4 entry-level SATA drives, or as many as 16 high-capacity 1TB drives. The data center has the ability to add new drives to the configuration as they are needed, or upgrade existing drives, as higher capacity models become available.
