Abstract
Crash-tolerant incremental change tracking between backups of a source storage. In one example embodiment, a method of crash-tolerant incremental change tracking between backups of a source storage includes assigning each block in a source storage into one of multiple zones, with each of the zones including multiple of the blocks, creating, in a nonvolatile storage, a nonvolatile zone map that represents each of the zones, and tracking, in the nonvolatile zone map, each of the zones that is changed between a first point in time and a second point in time. Each of the zones is marked as changed in the nonvolatile zone map upon the first receipt of a request to write to any of the blocks of the zone and prior to execution of the write request.
