An information management system is described herein that implements a data re-stubbing process. For example, a stub may have been previously migrated from one computing system to a network-accessible folder or to another computing system. The stub may be transparent to the user such that the user perceives the stub as being the actual data (e.g., when displayed). When a user selects the stub, the actual data may be retrieved and replace the stub. After some time, the actual data can be re-stubbed if not in use. If the actual data has not been modified since replacing the original stub, then the actual data can be replaced with the original stub. Otherwise, if the actual data has been modified since replacing the original stub, a new stub can be generated and replace the actual data.
