Abstract
Systems and methods are provided herein for garbage collecting data previously tiered to cloud storage. A cloud object index can be generated and used to track objects stored in cloud storage. As objects within cloud storage are added or modified, the transactions can be tracked and the cloud object index can updated based on the activity. Expiration dates associated with cloud objects can be maintained in the cloud object index factoring in user defined retention periods, process defined retention periods for services like backup and snapshots, and regulatory defined retention periods depending on the type of data being tiered. Upon a determination that no active processes are linking to a cloud data object, that an expiration date has been met, and other custom factors, cloud objects can be removed from cloud storage permanently.
