Abstract
A method, non-transitory computer readable medium, and device that assists with managing cloud storage includes identifying a portion of data in a data unit identified for deletion in the metadata. The identified portion of the data identified for delete is compare to a threshold amount. Deletion of the data unit from a first storage object is deferred when the determined portion of data identified for deletion is less than the threshold amount. A second storage object with a portion of data unmarked for deletion in the data unit is generated when the determined portion of data marked for deletion is equal to the threshold amount, wherein the second storage object has a same identifier as the first storage object.
