  • Snapshot cauterization
    Patent number: 9740701
    Abstract: Implementations disclosed herein provide for cauterizing portions of a snapshot. A file and/or directory or a set of files and directories of a snapshot can be identified via a user request or an automated process for cauterization. When cauterized, if a previous snapshot does not contain a ditto entry to the portion of the current snapshot that is requested to be cauterized, the BADDR associated with the cauterized portion of the snapshot can be freed for other storage use. In some implementations, metadata associated with the data that is cauterized can be retained for other uses.
