## Key points

- Yandex cannot restore 2.84% of customer data.
- The lost data may total about 100,000 terabytes.
- Customers using Yandex’s backup tools lost no data.

## Summary

Yandex says it cannot recover 2.84% of customer data stored in Yandex Cloud after attacks damaged its data centres. The loss highlights the risks to cloud customers when equipment is severely damaged and no separate backups are available.

The company restored access to 97.16% of the data; the unrecoverable portion may total about 100,000 terabytes and tens of millions of files. Yandex says customers who used its cloud backup tools retained all their data. In October, Ukrainian drones attacked three of Yandex’s six data centres, in the Ryazan region, Kaluga and Vladimir; replacing damaged equipment is estimated to take about six months.
