Yandex says it can't recover 2.8% of Yandex Cloud customer data after attacks

Yandex has admitted that some customer data in its cloud service is lost for good. The company says it cannot restore access to 2.8% of customer data in Yandex Cloud after Ukrainian attacks on its data centers.

The rest is back. Yandex engineers have recovered access to more than 97% of the data stored by customers on the platform.

Why can't the rest be saved?

According to the company, two things came together. The equipment holding that data was critically damaged. And the affected customers had no backup copy of their files on the platform.

In other words, for that 2.8% there is simply nothing left to restore from.

If you store anything important in the cloud, the lesson is an old one: keep a second copy somewhere else.
