Disk-based and cloud backups are network-reachable by design — and ransomware traverses networks. If your backup target shares a logical or physical path with the infected system, it is a potential encryption target. That is not a configuration problem; it is an architectural one.
What "Air-Gapped" Really Means
A physically ejected LTO cartridge has no IP address and no network interface. There is no path for malware to traverse. This is not a feature you configure or a policy you enforce — it is a structural property of the medium. Immutable object storage and WORM cloud buckets are useful hardening layers, but they remain network-reachable. An ejected cartridge is not.
Cloud Isn't a Backstop Either
Vendor durability guarantees are narrower than they appear. Researcher David Rosenthal's analysis shows that documented cloud data-loss events — MySpace's 50 million songs, Ultraviolet's 30 million user accounts — occurred despite robust infrastructure. Human error, malicious insiders, and vendor business decisions are outside the durability SLA. Egress costs compound the problem at recovery scale: retrieving a petabyte from deep cold cloud storage can cost more than a year of storage fees, at exactly the moment an incident demands speed.
LTO for M&E Archives
LTO-10 delivers 30 to 40 TB native per cartridge, and finished video compresses roughly 1:1 on tape — size for native capacity. Archival life runs approximately 30 years, versus 5 to 10 for spinning disk. WORM cartridges and AES-256 hardware encryption come standard, satisfying both ransomware resilience and content-governance requirements. MagStor's LTO drives and libraries are available across FC, SAS, and Thunderbolt connectivity, fitting into existing M&E workflows without retooling the ingest pipeline.
A single ejected cartridge per backup cycle is the one control ransomware cannot override. For M&E teams protecting irreplaceable masters, that physical isolation belongs in every 3-2-1 strategy. For more on air-gap architecture and LTO options, visit MagStor's FAQ page.
