What type of storage does OCI offer for long-term data retention?

The option for object storage is the ideal choice for long-term data retention in Oracle Cloud Infrastructure (OCI). Object storage is designed to store vast amounts of unstructured data, making it suitable for scenarios like backup and archival, where data needs to be retained securely over an extended period. It provides a highly scalable and durable solution, allowing users to store many terabytes or even petabytes of data without worrying about management overhead.

Object storage also offers features such as automatic data replication across availability domains, lifecycle management policies for data transition, and cost-effective pricing models, making it economical for storing data that is infrequently accessed yet must be retained for long durations.

In contrast, block storage is intended for storing data that requires high performance and low latency, like databases or applications that require fast read/write operations. File storage caters to shared file systems and is not optimized for long-term retention. Memory storage is ephemeral and generally used for temporary data that requires low-latency access, making it unsuitable for long-term data retention purposes.
