Managing data using purging

Abstract:

A system for managing data using purging includes an input interface and a processor. The input interface is to receive an indication of a data object to be purged. The processor is to prepare the data object to be purged, which includes severing weak relations of the data object as of a purge prepare time. Preparing the data object to be purged transitions the data object from an operational state to a purge prepared state. The weak relations of the data object are relations to non-purge data objects of an object tree. The data object in a purge prepared state is monitored for access. In response to a detection of an attempt to access the data object, reinstate the data object, which includes rebuilding the weak relations. Reinstating the data object transitions the data object from the purge prepared state to the operational state.
