Explanation
If a bare metal DB system requires more compute node processing power, you can scale up (increase) the number of enabled CPU cores in the system without impacting the availability of that system but you can't increase the storage If the original DB system VM shapeuses a single node, running databases on the DB system nodes are sequentially stopped and then restarted on the new shape so not dynamic

Explanation
You can copy objects to other buckets in the same region and to buckets in other regions.
You must have the required access to both the source and destination buckets when performing an objectcopy.
You must also have permissions to manage objects in the source and destination buckets.
Because Object Storage is a regional service, you must authorize the Object Storage service for each region carrying out copy operations on your behalf. For example, you might authorize the Object Storage service in region US East (Ashburn) to manage objects on your behalf. Once you authorize the Object Storage service, you can copy an object stored in a US East (Ashburn) bucket to a bucket in another region.
You can use overwrite rules to control the copying of objects based on their entity tag (ETag) values.
Specify an existing target bucket for the copy request. The copy operation does not automatically create buckets.
