Abstract

Users are increasingly demanding two contradictory system properties - the ability to absolutely, positively erase information so that it cannot be recovered, and the ability to recover information that was inadvertently or intentionally altered or deleted. Storage system designers now need to resolve the tension between complete delete and time machine computing.
