You are responsible for creating and maintaining an enterprise application that consists of multiple storage volumes across multiple compute instances in Oracle Cloud Infrastructure (OCI). The storage volumes include boot volumes and block volumes for your data storage. You need to create a backup for the boot volumes that will be done daily and a backup for the block volumes that will be done every week. How can you meet this requirement? A) Create clones of all boot volumes and block volumes one at a time. B) Group both boot volumes and block volumes in a volume group and create volume group backups. C) Create on-demand full backups of block volumes, and create custom images from the boot volumes. Use a function to run at a specific time to start the backup process. D) Create two volume groups for grouping boot volumes and block volumes separately. Create two custom backup policies as per requirement.
Answer (1)
To meet the requirement of creating backups for both boot volumes and block volumes in Oracle Cloud Infrastructure (OCI), option D is the most effective solution: Create two volume groups for grouping boot volumes and block volumes separately and create two custom backup policies as per requirement.
Here's a step-by-step explanation of why this option is suitable:
Volume Group Creation :
First, you will create two separate volume groups. One will consist of all the boot volumes, and the other will consist of all the block volumes used for data storage.
This separation allows for distinct backup policies tailored to the nature of the data held in these volumes.
Custom Backup Policies :
For the boot volumes, you would create a custom daily backup policy. This ensures that system configurations and applications on the boot volumes are consistently backed up every day.
For block volumes, a separate custom weekly backup policy should be established. Block volumes generally store data which might not change as frequently as system settings, making weekly backups sufficient in most cases.
Advantages of This Approach :
Automation : Custom backup policies allow you to automate the backup process, ensuring consistency and reducing the chance of human error.
Simplification : Managing backups via policies simplifies maintenance, especially as your infrastructure scales.
Cost-Efficiency : By tailoring the frequency of backups based on the type of volume, you can optimize costs associated with storage and data transfer during backups.
In contrast, other options either require more manual intervention, such as creating clones or custom images, or do not offer the tailored separation of boot and block volumes with distinct backup settings.
Implementing option D will help you efficiently manage your enterprise application's backup requirements within OCI.
