A Comparative TCO Study: VTLs and Physical Tape

This ESG study by Mark Peters evaluated a common industry-standard disk VTl deduplication system (with 15:1 reduction ratio) versus a tape library with LTO-5, drives with full nightly backups, over a five-year period. The scenarios included replicated systems and offsite tape vaults. In all circumstances, the TCO for VTL with deduplication ranged from about 2 to 4 times more expensive than the LTO-5 tape library TCO. The paper shares recent ESG research and lots more.
