Abstract As organizations transition to hybrid and multi-cloud architectures, the total cost of ownership (TCO) for data protection becomes increasingly complex. The Veeam Cost Calculator is a strategic tool designed to model, compare, and optimize expenses associated with Veeam’s Availability Suite versus legacy or alternative backup solutions. This paper analyzes the calculator’s core modules—capacity, compute, storage, and cloud mobility—and provides guidance on interpreting its outputs for financial planning and vendor selection. 1. Introduction Data protection costs extend beyond software licensing. Hardware, storage tiers, network bandwidth, cloud API fees, and operational overhead often create hidden liabilities. Veeam’s interactive cost calculator (available via Veeam partners and official website) addresses this by enabling IT financial planners to model deployment scenarios: on-premises, Veeam Cloud Connect, or fully cloud-native (Veeam Backup for AWS/Azure/Google Cloud). 2. Key Input Categories The calculator requires the following inputs to produce a reliable estimate:
