Abstract
A computer system, such as a data storage system, implements techniques for deleting durably stored data without affecting the availability or durability of other data associated therewith. In some embodiments, data is encrypted prior to redundancy coding such that deletion of an encryption key used to encrypt the data renders that data inaccessible, but other data bundled in the same redundancy coded bundle remains available. In such embodiments, a shard containing deleted data may still be usable to regenerate other, non-deleted or live data still extant in the same bundle of shards.
