Embodiments for optimizing data storage instances in a cloud environment in which metadata is stored and accessed separately from content data in multiple different instances of data storage units. A metadata and content data storage instance optimization process determines the status of different instances of virtual storage resources for both metadata and content data. Full instances are powered down when they are not needed, empty instances are deleted, and data of partially full instances is moved to other appropriate instances to create empty instances that can be deleted. The data storage instance optimization process is provided as part of a data protection search process that provides an execution environment and user interface to the optimization process.
