Which OCI service is the most cost-effective for migrating old database backups?

Choosing Archive Storage for migrating old database backups is the most cost-effective solution in Oracle Cloud Infrastructure. Archive Storage is specifically designed for large-scale data retention at a low cost, making it ideal for data that is infrequently accessed, such as old backups.

This storage class offers very low pricing for storing large amounts of data, which is a significant advantage when dealing with backups that do not require immediate or frequent access. Additionally, Archive Storage provides durability and security, ensuring that your data is safe while minimizing expenses.

In contrast, options like Object Storage, Block Volume, and File Storage can be more expensive for long-term data retention. Object Storage is more suited for active data access and retrieval, Block Volume offers performance for workloads where data needs to be frequently accessed or modified, and File Storage is optimized for file sharing and collaboration. When the main goal is the cost-effective long-term retention of infrequently accessed data, Archive Storage stands out as the best choice.
