Oracle Exam 1Z0-1072 Topic 1 Question 13 Discussion

You can create a clone from a volume using the Block Volume service. Cloning enables you to make a copy of an existing block volume without needing to go through the backup and restore process.

A cloned volume is a point-in-time direct disk-to-disk deep copy of the source volume, so all the data that is in the source volume when the clone is created is copied to the clone volume.

You can only create a clone for a volume within the same region, availability domain and tenant. You can create a clone for a volume between compartments as long as you have the required access permissions for the operation.

during create a clone you can do the following

If you want to clone the block volume to a larger size volume, checkCustom Block Volume Size (GB)and then specify the new size. You can only increase the size of the volume, you cannot decrease the size. If you clone the block volume to a larger size volume, you need to extend the volume's partition. SeeExtending the Partition for a Block Volumefor more information.

If you want to change the elastic performance setting when cloning the volume, checkCustom Block Volume Performanceand select the elastic performance setting you want the volume clone to use. SeeBlock Volume Elastic Performancefor more information. You can also change the elastic performance setting after you have cloned the volume, seeBlock Volume Elastic Performance. If you leaveCustom Block Volume Performanceunchecked, the cloned volume will use the same elastic performance setting as the source volume.
