The rise of ransomware has highlighted the need for air-gapped backups, and data tapes have become the most popular tools for fighting back.
The United States Cybersecurity and Infrastructure Security Agency (CISA) recommends offsite, offline backups as a ransomware mitigation strategy, noting that most ransomware infections cannot be resolved without restoring from a backup (or paying the ransom, which can exceed $1 million for high-value targets). Modern tape formats are an inexpensive and highly dependable way to create these backups, and many enterprises have quickly adopted current-generation formats like LTO-9 to build their disaster recovery strategies.
However, your enterprise cannot adequately prepare for ransomware infection by simply creating one-off backups. To build a strategy that works — and avoid costly remediation during an attack — it’s important to understand how tape backups address the problem. Here are a few considerations to keep in mind.
