Abstract
In a parity-based redundancy scheme, a log is maintained that contains a record of storage writes and associated redundancy backups. A mapping of allocation information indicative of free and allocated portions of storage is stored. An indication is received of a change to the free and allocated portions of storage. An update to the mapping of allocation information is determined, and the update to the mapping of allocation information is stored. The stored update is accessed and the redundancy backup is synchronized with stored data in response to a power interruption.
