Abstract

A technique includes receiving a request to restore a state of a file system. The request defines a rollback period, which extends from a restoration time that is specified by the request to a time at which the request was made. The technique includes reconstructing a state of the file system in response to a query using a preserved snapshot of the file system. The reconstruction including reconstructing the state at an arbitrary query time based at least in part on a dynamically inheritable attribute of an entity stored on the file system and the rollback period.
