1Z0-1072-25 Question 206
Single answerYour team manages a mission-critical application in Oracle Cloud Infrastructure (OCI) whose data is distributed across multiple block volumes attached to individual compute instances. To satisfy your organization's business continuity policies, you need to perform a single consistent backup for all these volumes simultaneously, with minimal administrative overhead. Which approach should you use to achieve this goal?
- A
Create a Volume Group that includes all block volumes and perform a Volume Group Backup.
- B
Back up each volume individually at different times using separate block volume backups.
- C
Use the File Storage service to back up each block volume� data from a file share.
- D
Manually copy data from each block volume to object storage using custom scripts.
Show answer and explanation
Correct answer: A
Explanation
Using Volume Groups in OCI ensures you can create a consistent backup of multiple block volumes with a single operation. This approach is recommended by Oracle because it reduces administrative overhead and guarantees a synchronized point-in-time snapshot across all volumes in the group. Refer to the Oracle Cloud Infrastructure Block Volume documentation for best practices on creating and managing Volume Groups, Volume Group Backups, and Volume Group Clones.
- A. Correct.
Option 1 is correct. Volume Groups allow you to manage and back up multiple block volumes as a single logical entity, ensuring a consistent point-in-time snapshot across all volumes in the group. This is the recommended approach for multi-volume applications that require synchronized backups.
- B. Incorrect.
Option 2 is incorrect. Performing separate backups for each volume risks data inconsistency because they won�t all share the same point-in-time snapshot. Even small timing differences can result in inconsistent data states across volumes.
- C. Incorrect.
Option 3 is incorrect. The File Storage service is a separate OCI service designed for file-based workloads and does not provide a synchronized backup mechanism for block volumes. You can't directly use File Storage to back up block volume data in a consistent snapshot fashion.
- D. Incorrect.
Option 4 is incorrect. Manually copying or scripting backups to Object Storage each time is labor-intensive and can lead to inconsistent backups if the volumes are not snapped simultaneously. It also does not leverage OCI� native capability for creating volume group snapshots.
