A three‑column checklist compares backup vendors across five categories: technical capability, security and compliance, total cost of ownership, strategic alignment and support and operations. Each row lists key considerations -- RTO/RPO performance, ransomware defenses, multi‑year costs and egress fees, data portability and support coverage -- and ends with a critical question to test real‑world readiness. Use it to validate disaster‑scenario performance, SOC integration and vendor exit options.
