If the Oracle database is in archive log mode, the redo logs are copied as archive files. Archive files will be transferred to the directory or disk group specified by the db_recovery_file_dest parameter.
You can use the following query to check how much archive log is generated daily. The query result will give the total generated archive log size in mb per day.
