The technology described herein is directed towards processing data that is protected by a preliminarily protection scheme (e.g., triple mirroring) before re-protecting that data via erasure coding. Data of new or updated objects, which can be segmented in one or more preliminarily protected data chunks (a data inbox), is consolidated to put the object's data segments in contiguous space. The consolidated object data can be compressed, and erasure coded (possibly along with consolidated and compressed data of one or more other objects) into data fragments and coding fragments of a distributed destination data chunk. Once an object is stored via erasure coding, the source chunk or chunks no longer contain live data of that object; when a source chunk contains no live data of any object, the capacity of the source chunk (and any mirror copies) can be reclaimed.
