Abstract
A method assigns stored documents within a distributed storage system (DSS) to various document categories to enable a target number of documents to be deleted. An intelligent storage management (ISM) utility identifies a data storage threshold value used to control data storage within the DSS. If a current storage usage exceeds the data storage threshold value, the ISM utility calculates, based on the current storage usage, a target number of documents that can be deleted from the DSS. The ISM utility utilizes a recursive process which includes assigning stored documents to groups including a set of document categories based on data characteristics of the stored documents. The ISM utility further utilizes the recursive process to delete, based on an established ordering of the groups, all of the stored documents assigned to a subset of the groups in order to remove the target number of stored documents.
