1. An apparatus for automated data purge in an electronic discovery (e-discovery) system, the apparatus comprising:

  • a computing platform including a memory and at least one processor in communication with the memory;

    a data purge application stored in the memory, executable by the processor and configured to;

    determine one or more purge-eligible e-discovery cases by querying an e-discovery system metadata database with predetermined purge criteria to determine one or more purge-eligible cases,determine (1) files within an e-discovery file system that are associated with the purge-eligible cases and qualify for purging based on identified purge policies, wherein the purge policies include at least (i) purging e-discovery work product data based on an associated case being closed, (ii) purging all data associated with a closed case after a predetermined period of time, and (iii) purging data stored at an external repository after a predetermined period of time commencing from a date, and (2) storage locations within the e-discovery file system associated with the files by querying an e-discovery system metadata database with the purge policies,determine replicated source data files within the e-discovery file system that are associated with the purge-eligible cases and qualify for purging by scanning an e-discovery system file directory to identify the replicated source data files that qualify for purging based on the one or more identified purge policies,purge data from (1) the storage locations within the e-discovery file system associated with the files, and (2) the replicated source data files, andin response to purging the data, automatically (1) update the e-discovery file system to reflect that the data has been purged by creating a purge entry in a file system log that includes details of the data purge, and (2) update metadata that is stored in an e-discovery system metadata database and associated with the purged files, to indicate that the data has been purged and is no longer accessible.
