Your organization has deployed a large, complex application across multiple compute instances in Oracle Cloud Infrastructure (OCI). These compute instances also have block volume storage attached to them. You want to create a time consistent backup of these block volume storage. Which implementation strategy should be used?
A. Create a manual backup of each volume
B. Use scripts available in OCI to backup block volume storage
C. Group volumes in a volume group first and then use available scripts in OCI
D. Group volumes in a volume group and create a manual backup of the volume group

Why D and not C? Both D & C mention backing up volume groups, but D is manual and C is using scripts – so why manual ?
There’s no existing scripts. Manual means click a button from OCI console
Ans : D
The Oracle Cloud Infrastructure Block Volume service provides you with the capability to group together multiple volumes in a volume group. A volume group can include both types of volumes, boot volumes, which are the system disks for your Compute instances, and block volumes for your data storage. You can use volume groups to create volume group backups and clones that are point-in-time and crash-consistent.
This simplifies the process to create time-consistent backups of running enterprise applications that span multiple storage volumes across multiple instances. You can then restore an entire group of volumes from a volume group backup.
