What is an effective solution for quick recovery from ransomware attacks?

Volume snapshots are an effective solution for quick recovery from ransomware attacks because they allow organizations to create point-in-time copies of data stored on disk volumes. When a ransomware attack occurs, the malware typically encrypts files, making them inaccessible to users. However, if volume snapshots have been taken regularly, an organization can revert to the most recent clean snapshot to restore access to its data. This process can be done quickly, minimizing downtime and data loss.

Snapshots provide a level of granularity in recovery, enabling restoration of specific files or entire volumes based on the last known good state before the attack. This makes them especially valuable in crisis scenarios, where minimizing disruption to business operations is crucial. By using volume snapshots as part of a broader backup and recovery strategy, organizations enhance their resilience against such attacks.

Other options like data encryption and redundant backups are important for data security and recovery, respectively, but they do not offer the same level of immediacy and ease in restoration as volume snapshots. Application failover is focused on maintaining service availability rather than directly addressing data recovery from specific incidents like ransomware. Thus, volume snapshots stand out as a practical, efficient method to mitigate the impacts of ransomware on data recovery.
