Abstract:
Many data centers of the Russian technology company Yandex were attacked by Ukrainian drones in October. Physical attacks usually cause damage to data centers, so Yandex mobilized an engineering team to repair the hardware and try to restore the data center afterwards.
After more than 30 days of emergency repairs, these damaged data centers have basically resumed work. However, some hardware damage in the data centers has resulted in data loss, and the data cannot be recovered (because Yandex does not enable the backup function by default).
Yandex Cloud recently issued the latest announcement stating that its engineering team has restored 97.16% of customer data, and the remaining 2.84% cannot be restored due to severe hardware damage and the customer's lack of backup on the platform. By default, the backup mechanism of Yandex Cloud cloud servers/virtual machines is not enabled.
The company said that if customers have used the backup tools provided by the cloud platform, the data can be restored. The backup methods provided by Yandex Cloud include cloud backup, disk snapshots and managed database backup. When these functions are turned on, they require additional resources and require customers to pay.
After the data center was attacked, Yandex Cloud also adjusted its operating strategy and decided to enable the backup mechanism for all newly created virtual machines or servers. Since the backup mechanism will occupy additional resources and incur costs, Yandex recommends that users arrange their own backup strategies. If not, they can turn off backup in the console.
In addition, Yandex will activate availability zone F of the Central Russia 1 data center on November 11, and some computing resources will be deployed to the new availability zone. Resource quotas are set initially when a new region is enabled, so some network functions will continue to be processed in other availability zones.
