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 six hours.
How can you meet this requirement?
To meet the requirement of creating a daily backup for boot volumes and a backup every six hours for block volumes, you need to create two separate volume groups: one for boot volumes and one for block volumes. This allows you to apply distinct custom backup policies to each volume group based on the specified frequency. Grouping them together in a single volume group would not allow separate backup schedules, and creating clones or on-demand backups manually does not meet the automation requirement.
In my understanding, when you create a volume group, you can add multiples boot and block volumes, and then associate it just one policy backup. I've implemented in my tenants option described in C option. Someone with a different experience?
C. Per https://docs.oracle.com/en-us/iaas/compute-cloud-at-customer/topics/block/assinging-a-backup-policy-to-a-volume-or-volume-group.htm, a volume or volume group can have only one backup policy assigned
