          1)this you can check from your old backup size.add a little to it and that is your backup space requirement.
          2)if space is not there then failed backup is corrupt.other old backups remain intect.
          3)you need to shutdown database for copying folder or put data files in backup mode(id archivelogs are enable on database).
          4)you can check original database files dba_data_files,v$controlfile views and as point 3 is valid on them if you using copy paste rather then RMAN.
          5)when taking backup from rman use
          RMAN> RUN {
            FORMAT '/u01/backups/%U';
            RELEASE CHANNEL;
          In format clause you can give disk location.
