The Oracle Cloud Infrastructure (OCI) Object Storage service is an internet-scale, high-performance storage platform where you can safely and securely store or retrieve data directly from the internet or from within the cloud platform.

In OCI Object Storage, Buckets are logical containers for storing data or objects. A bucket is governed by security policies to secure your backups from unauthorized access. Retention rules, applied to buckets, provide regulatory compliance and protect data from malicious damage.

The Archive storage tier is "cold" storage used for data seldom or rarely access, but that must be retained and preserved for long periods of time.

By default, Buckets are encrypted with keys managed by Oracle.

You configure your RMAN environment to send RMAN database backups to the OCI Object Storage buckets. You can then use familiar Recovery Manager (RMAN) commands to perform backup, restore, recovery, and maintenance operations. You can preserve RMAN backups by storing the backups in immutable buckets.

Protected databases backing up to a Recovery Appliance that archives to Object Storage. Recovery Appliance also uses the Database Cloud Backup Module to archive backups to Oracle Cloud for long term storage. The Oracle Key Vault (OKV) contains the TDE master keys for each protected database.

Oracle Cloud Databases can enable the OCI-managed automatic backups to Object Storage. You must use a service gateway to enable Oracle Cloud Databases to access Object Storage for backups. A service gateway allows connectivity to the Object Storage public endpoints from private IP addresses in private subnets.

Object Storage offers distinct storage class tiers to address the need for both performant, frequently accessed "hot" storage, and rarely accessed "cold" storage.

Every object uploaded to Object Storage is assigned to a storage tier. The storage tier property of the object determines its storage costs and any associated retrieval fees.

The Standard tier is the primary, default storage tier used for Object Storage service data. The Standard storage tier is "hot" storage used for data that you need to access quickly, immediately, and frequently. Data accessibility and performance justifies a higher price to store data in the Standard tier.

The Archive tier is the primary, default storage tier used for Archive Storage service data. The Archive storage tier is "cold" storage used for data seldom or rarely access, but that must be retained and preserved for long periods of time.

You choose a default storage tier (Standard or Archive) when you create a bucket. When set at bucket creation, you cannot change the default storage tier for a bucket.

Object Storage enables you to configure retention rules at the bucket level and are applied to all individual objects in the bucket. Retention rules provide immutable, WORM-compliant storage options for data written to Object Storage and Archive Storage for data governance, regulatory compliance, and legal hold requirements. Retention rules can also protect your data from accidental or malicious update, overwrite, or deletion. Retention rules can be locked to prevent rule modification and data deletion or modification even by administrators.
