  38. channel ORA_DISK_1: backup set complete, elapsed time: 00:00:15
  39. Finished backup at 12-MAR-16

该命令的意思是：备份没有备份过两次的归档日志，前面的所有归档日志只备份过一次，所以都备份。

再看下面的命令

  1. RMAN> backup archivelog all not backed up 1 times;
  2. Starting backup at 12-MAR-16
  3. current log archived
  4. using channel ORA_DISK_1
  5. skipping archived logs of thread 1 from sequence 5 to 32; already backed up
  6. channel ORA_DISK_1: starting archived log backup set
  7. channel ORA_DISK_1: specifying archived log(s) in backup set
  8. input archived log thread=1 sequence=33 RECID=29 STAMP=906292883
  9. channel ORA_DISK_1: starting piece 1 at 12-MAR-16
  10. channel ORA_DISK_1: finished piece 1 at 12-MAR-16
  11. piece handle=/u01/app/oracle/fast_recovery_area/ORCL/backupset/2016_03_12/o1_mf_annnn_TAG20160312T120123_cg754mrr_.bkp tag=TAG20160312T120123 comment=NONE
  12. channel ORA_DISK_1: backup set complete, elapsed time: 00:00:01
  13. Finished backup at 12-MAR-16

1 times与不加1 times的效果是一样的，即备份过一次及以上的归档都不归档，在此处，新产生的33号归档日志没有备份过，因此备份33号归档日志。
