How is data redundancy achieved in OCI Object Storage?

Data redundancy in OCI Object Storage is primarily achieved by ensuring that data is replicated across multiple availability domains. This means that when data is stored, it is automatically backed up in different physical locations within the cloud infrastructure. This replication serves several purposes: it provides high availability, ensures durability, and protects against data loss due to failures in a specific availability domain.

When data is replicated across multiple availability domains, it allows for seamless access to the data even if one domain becomes unavailable. This design helps in maintaining business continuity and ensuring that applications relying on this data can operate without interruption.

The other options do not align with how data redundancy is implemented in OCI Object Storage. RAID configurations, typically used for physical disk management, are not applicable in a cloud object storage context. Local backups, while a useful practice, do not contribute to redundancy in the same way that replication across availability domains does. Limiting data access pertains to security and access controls rather than redundancy, which focuses on ensuring data is duplicated and available across different locations.
