📼Tape Storage

NEW

Magnetic tape used for high-capacity, low-cost, long-term archival and backup storage.

DESCRIPTION

Tape storage provides durable, cost‑effective archival for large datasets, typically with high sequential throughput and low random access performance. Modern LTO generations offer long media longevity and native encryption. Tape supports air‑gap strategies against ransomware and can enforce WORM retention for compliance. It is used for backups, deep archives, and disaster recovery vaulting. While access latency is higher than disk or cloud object storage, tape’s economics excel at petabyte‑scale archives.
