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 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 backing up boot volumes daily and block volumes every six hours, it is necessary to create separate custom backup policies for each type of volume. Grouping the boot volumes into a volume group and creating a custom backup policy allows the daily backups, while grouping the block volumes and creating a separate custom backup policy allows the backups every six hours. This approach ensures that the different backup schedules are maintained as required.
why A is not an answer?
Agree with jsh96, it is possible to group boot and block volumes together in volume group and backup them in one go, but requirements in this task was two different backup timings. That's why I vote A.
A is correct. @NamNT We can schedule it for every 6 hour like we can daily with 0,6,12,18,0,6....... hour.
Correct Answer A
When we define backup policy, there is no any option for "backup for the block volumes that will be done every six hours", confuse?????
A would be correct since required is to backup at different times and not at same time.
C is correct because https://docs.oracle.com/iaas/Content/Block/Concepts/bootvolumes.htm
You can group boot volumes with block volumes into the same volume group, making it easy to create a group volume backup or a clone of your entire instance, including both the system disk and storage disks at the same time.
A is correct
