This Quantum white paper highlights tape backup as a critical last line of defense against ransomware. It details how attacks like WannaCry and Locky exploit systems through email links and social engineering, often targeting backups first. The paper emphasizes a 3-2-1-0 backup strategy: 3 copies, 2 media types, 1 offsite, and 0 online access. Cloud backups can still be compromised via sync and stolen credentials. Offline tape storage, in contrast, is immune to network-based attacks. Quantum’s DXi deduplication appliances and Scalar tape systems support fast, secure backups and cost-effective, long-term data retention.
