Abstract
Generation of new snapshots of a storage object are prompted based on changes to the storage object. An absolute storage change condition is satisfied when the aggregate amount of changed data since the most recent snapshot satisfies a threshold that represents a predefined amount of storage capacity, e.g., N GB. A percentage of used storage change condition is satisfied when the aggregate size of the changes expressed as a percentage of the provisioned storage capacity of snapped storage object satisfies a predetermined threshold, e.g., X % of Y TB. A percentage of provisioned storage change condition is satisfied when the aggregate amount of the changes in terms of percentage of utilized storage capacity of storage object satisfies a predetermined threshold expressed as a percentage of the utilized capacity of the storage object, e.g., P % of Z TB.
