In Oracle Cloud Infrastructure (OCI), backup options are designed to be "set-and-forget." Because OCI uses a highly distributed architecture, your backups are typically stored in a separate, durable storage tier (Object Storage) that is physically independent of your compute servers.

Here are the primary backup options available for your rented infrastructure in 2026:

1. Block and Boot Volume Backups

This is the most common backup type for your servers. It captures a point-in-time "image" of your virtual or bare metal disks.

• Automated Policy-Based Backups: You can assign "Policy" tiers to your volumes. OCI provides three default schedules:

  • Bronze: Monthly backups retained for one year.

  • Silver: Weekly backups retained for four weeks.

  • Gold: Daily backups retained for seven days, plus weekly/monthly increments.

• Manual Backups: You can trigger a one-off backup at any time before making a major change to your server.

• Cross-Region Copies: You can automatically copy backups to a different geographical region (e.g., from US-East to US-West) for disaster recovery.

2. Volume Group Backups (Consistency is King)

If your application or database (like SQL Server or MongoDB) stores data across multiple volumes, backing them up individually can lead to "data skew."

• What it is: You group multiple volumes together.

• The Benefit: OCI freezes the I/O across all disks simultaneously, takes a coordinated snapshot, and resumes. This ensures the backup is "crash-consistent" across the entire stack.

3. Database-Specific Backups

Oracle’s "Crown Jewel" services have their own specialized backup engines that go deeper than simple disk snapshots:

• Autonomous Database: Backs up automatically every 24 hours with a 60-day retention. It also allows "Point-in-Time Recovery" (PITR) down to the specific second.

• Base Database Service: Uses RMAN (Recovery Manager) to back up directly to Object Storage. You can choose to have Oracle manage it or script it yourself.

4. File Storage Snapshots

For the File Storage Service (NFS), backups are handled via Snapshots.

• Copy-on-Write: These are nearly instantaneous and take up no extra space until data is modified.

• User Recovery: Users can browse a hidden .snapshot directory to recover their own files without needing a cloud admin.

6. The "Backup Strategy" Pro-Tips

• Incremental Forever: OCI backups (after the first one) are incremental. You are only charged for the storage of the changed data blocks, not the full size of the disk every time.

• Immutable Backups: In 2026, OCI supports Retention Rules on the buckets where backups are stored. This means even a compromised Admin account cannot delete your backups until the retention period expires—a critical defense against Ransomware.

• Cost Efficiency: You can move older backups to Archive Storage. It costs significantly less ($0.0018 per GB) but takes a few hours to "thaw" when you need to restore.
