The database increases by 50-80g each month and the recent data which
are readonly are saved in primary storage device(harddisk).
when the data are older than one year,we want to move them from
primary storage device to secondary storage device(CDs) instead of
importing & exporting.
The tables are partitioned for each month data.
Any suggustions?
