Yandex Cloud Data Recovery Reaches 97% After Drone Strike
Russian technology giant Yandex has restored operations across multiple data centers following physical drone attacks in October. Specifically, Ukrainian drone strikes inflicted severe structural damage on these facilities, prompting Yandex to mobilize emergency engineering teams. After more than thirty days of intensive hardware repairs, the affected facilities have largely resumed normal operations. Nevertheless, extensive physical destruction caused permanent loss of some unbacked customer records. Overall, this massive Yandex Cloud data recovery effort highlights the vital role of resilient infrastructure backups.
Hardware Destruction and Unrecoverable Customer Records
In a recent status update, Yandex Cloud announced that engineers successfully restored 97.16 percent of customer data. However, the remaining 2.84 percent proved unrecoverable due to severe hardware destruction and missing platform backups. Historically, Yandex Cloud virtual machines and cloud servers did not activate automated backups by default. As detailed in the official Yandex Cloud recovery update, customers who configured platform backup tools recovered everything. Specifically, these paid options included Cloud Backup, disk snapshots, and managed database backups. Because these features consume extra compute resources, many subscribers previously left them disabled.
New Default Backup Policy for Virtual Machines
Following the October physical intrusions, Yandex Cloud overhauled its core operational resilience strategy. Going forward, the cloud provider activates automated backups by default on all newly provisioned virtual machines. Because automated snapshots consume additional storage resources and incur service fees, Yandex advises administrators to review their policies. Consequently, users who prefer custom protection schemes can disable default backups inside the management console.
Expanding Regional Capacity with Availability Zone F
Additionally, Yandex launched Availability Zone F within its Central Russia 1 data center region on November 11. Engineers are actively deploying fresh compute workloads into this newly established infrastructure zone. Because the new zone operates under initial resource quotas, other availability zones still handle certain networking functions. Ultimately, mandatory default backups and expanded regional redundancy strengthen cloud resilience against physical infrastructure disruptions.
