From Enterprise Vault 8.0 SP3 onwards, FSA Reporting includes an FSA Reporting database purging job. The purging job moves data from the database's main tables to the history tables.
By default the FSA Reporting database purging job runs daily at midnight. You can change the schedule for the purging job if required.
