Abstract
A request to restore a primary system to a backed-up state of the primary system that is associated with a particular point in time is received at a storage system. The backed-up state of the primary system corresponds to a particular backup snapshot. The primary system is determined to be corrupted less than a threshold amount of corruption. An indication of a first set of changes that includes one or more changes to the primary system that have occurred since a last backup snapshot is received. A second set of changes that includes one or more changes between the particular backup snapshot and the last backup snapshot is determined. It is determined, based in part on the indication of the first set of changes, which data associated with the second set of changes to provide to the primary system. The determined data is provided to the primary system.
