Comparison of Local and Cloud Backup Storage

Backing up your DB system is a key aspect of any Oracle database environment. You can store backups in the cloud or in local storage. Each backup destination has advantages, disadvantages, and requirements that you should consider, as described below.

For more information on backup and recovery, see Back Up and Recovery in Base Database Service.

Recovery Service (Recommended)

  • Backups are stored as protected databases in Recovery Service.
  • Durability: High
  • Availability: High
  • Back Up and Recovery Rate: High
  • Advantages: High durability, performance, and availability.

Object Storage

  • Backups are stored in the Object Storage.
  • Durability: High
  • Availability: High
  • Back Up and Recovery Rate: Medium
  • Advantages: High durability, performance, and availability.

Local Storage

  • Backups are stored locally in the Fast Recovery Area of the DB System.
  • Durability: Low
  • Availability: Medium
  • Back Up and Recovery Rate: High
  • Advantages: Optimized back up and fast point-in-time recovery.
  • Disadvantages: If the DB System becomes unavailable, the backup is also unavailable.

Currently, OCI does not provide the ability to attach block storage volumes to a DB System, so you cannot back up to network attached volumes.
