Access "Sizing up VTLs"

Published: 19 Oct 2012

Virtual tape libraries can speed backups and restores, but VTL products vary widely and the differences are sometimes subtle. Initially developed for mainframes, virtual tape systems, which emulate tape libraries to a backup server, are becoming an important part of the shift toward disk-based data protection. Virtual tape libraries (VTLs) present disk as tape, so the normal backup media server can perform backups as usual, regardless of the physical backup infrastructure. There are two major types of virtual tape architectures: bundled appliances that include virtualization software and disk storage, and virtual tape software that runs on a server platform with a variety of back-end storage devices. An appliance provides higher levels of integration and reduces the operational complexity of deployment and administration. A software-only approach offers more flexibility and investment protection because it enables storage administrators to leverage their existing server and storage infrastructure to deploy virtual tape. In general, an appliance may be more ... Access >>>
