backup of schema using extract

Hi

I am trying to create backup of the extract schema tables by appending cob_dt to table name. I get all the extract tables in my cursor.Then I process these tables one by one.Butafter creation of these backup tables..the backup tables too get into the cursor and a backup of the backup table is created which i dont want. I just want backup of the extract tables and not backup of the backup tables
