Mitigating the risk of threats and data loss involves comprehensive planning and the application of multiple techniques. Tape air gap is a recommended technique, as it protects critical data better against cyber attacks.
An air gap will ensure that, at any given time, one copy of data is offline (disconnected) and cannot be accessed. If one file or folder has no connection to the Internet or a LAN, it basically cannot be remotely hacked or corrupted, hence the air gap will effectively prevent cyber attacks since data stored offline cannot be hacked.
In a white paper titled “Using Tape to Optimize Data Protection Costs and Mitigate the Risk of Ransomware for Data-Centric Organizations.”, the IDC’s Phil Goodwin writes:
“Recently, tape has shown itself to be an effective means of providing an ‘air gap’ between live data and protected data,”
He mentioned that an air gap created by an tape-based storage systems provides protection against cyber criminals attempts to compromise production systems, in those that would otherwise be vulnerable to ransomware attacks.
Tape has been recognized as the most cost-effective means of storing data for long-term retention and an effective means of providing an air gap between live data and protected data. This air gap is essential to thwarting more sophisticated ransomware and malware that attempts to corrupt live, backup, and archive data simultaneously. (Note: cloud backups may also become a virtual, modern equivalent of air-gapped tape backup, but ONLY IF they are truly disconnected.). Tape is considered as the best offline backup solution for creating an air-gap to keep business critical data available even in the case of ransomware and other cyber attacks.
Tape is not only still alive and kicking today, but it also proven to provide effective protection against modern cyber attacks.
