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?
A. Group both boot volumes and block volumes in a volume group and create volume group backups.
B. Create clones of all boot volumes and block volumes one at a time.
C. Create two volume groups for grouping boot volumes and block volumes separately. Create two custom backup policies as per requirement.
D. 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.
