Backup

Backup is the process of creating copies of specific data or system states to be stored on independent media, such as external drives, tapes, or cloud storage. This ensures that if the original data is lost due to hardware failure, cyberattacks (like ransomware), or natural disasters, it can be restored. According to ISO 22301 and NIST CSF (Protect Function), backup is a critical control for ensuring information availability. Unlike archiving, which focuses on long-term storage, backup is optimized for rapid restoration. In the context of the GDPR (Article 32) and Taiwan's Personal Data Protection Act, backup is a necessary technical measure to ensure the ongoing availability and resilience of processing systems. A robust backup strategy must be validated through regular restoration tests to be considered effective in a Business Continuity Management (BCM) framework.

Implementation follows a three-step methodology. First, Business Impact Analysis (BIA) is conducted to define RTO (Recovery Time Objective) and RPO (Recovery Point Objective) for each critical process. For example, a financial institution may require an RPO of zero for transactions, while HR records might allow a 24-hour RPO. Second, a multi-tier backup architecture is deployed, typically following the 3-2-1 rule: three copies of data, two different media types, and one offsite. This includes both on-premises and cloud-based solutions to mitigate regional disasters. Third, regular recovery drills are performed to verify the integrity of backup-and-restore procedures. A real-world example is the 2021 ransomware attack on a major Taiwanese telecom provider, where companies with verified offsite backups recovered within hours, while those without saw weeks of downtime. Quantifiable benefits include a 70% reduction in potential downtime and a significant decrease in regulatory fines by meeting compliance standards.

Taiwan enterprises face three primary challenges. First, the complexity of multi-cloud and hybrid environments makes data-siloing a major risk; the solution is to implement a unified backup management platform. Second, the shortage of certified BCP professionals in Taiwan leads to poorly documented recovery procedures; this can be addressed through ISO 22301 certification training and outsourcing to specialized consultants. Third, the cost of high-speed, offsite backup solutions often deters SMEs. To overcome this, companies should adopt a phased approach: starting with critical systems first, then expanding to less critical data as budget allows. The priority should be: Month 1: Asset inventory and RTO/RPO definition; Month 2: Implementation of offsite/cloud backup; Month 3: Full-scale recovery drill. This structured approach typically results in a 90% improvement in recovery-readiness within the first year.
