Yandex says 2.84% of Yandex Cloud client data cannot be recovered

According to Yandex's explanation, the unrecoverable portion of the data is due to two reasons: the equipment suffered critical damage, and the owners of this data had no backups on the platform. Clients who used Yandex Cloud backup tools lost nothing, the company stated. Earlier, as iXBT.com writes, Yandex had reported restoring access to approximately 90% of data.

Following the incident, the cloud platform changed its approach to backups. Previously, clients had to enable backups manually; now, when creating a new virtual machine, it is activated automatically. The terms of service remain unchanged, and users can opt out.

Engineers are distributing Yandex Cloud computing capacity across new independent sites in various regions of Russia, and the number of such locations will grow, the company stated. The Lyapunov, Galushkin and Chervonenkis supercomputers were not damaged, according to Yandex: they were relocated from their previous sites and are being deployed at new facilities as separate clusters.

As 3DNews writes, three Yandex data centres — in Sasovo in Ryazan region, Kaluga and Vladimir — were damaged between October 8 and October 11 as a result of drone attacks. According to Interfax information cited by the publication, the centres in Sasovo and Vladimir shut down operations entirely, while several modules failed in Kaluga.
