Before you start a purge, back up all affected datastores and file systems. If you run scheduled purges, you can write code that uses the PurgingService event listener to trigger the required backup operations.
After executing a purge, you might need to repair database indexes, especially if a large amount of versioned data is removed. This is often the case the first time you purge versioned data. Other database-specific considerations might apply. For example, given an Oracle database, a purge that includes millions of asset versions might require a large undo tablespace; DB2 might require large buffer pools. For more information, consult your database system documentation.
