Google Cloud Storage stores objects (originally limited to 100 GiB, currently up to 5 TiB) in projects which are organized into buckets.

[5] Google Cloud Storage provides a durability guarantee of 99.999999999% (referred to as "11 nines"), primarily addressing data loss from hardware failures.

However, this guarantee does not extend to losses resulting from human errors (such as accidental deletion), misconfigurations, third-party failures and subsequent data corruptions, natural disasters, force majeure events, or security breaches.

Customers are responsible for monitoring SLA compliance and must submit claims for any unmet SLAs within a designated timeframe.

In cases of data loss due to hardware failure attributable to Google Cloud Platform, the company does not provide monetary compensation; instead, affected users may receive credits if they meet the eligibility criteria.
