第二次备份归档日志

点击(此处)折叠或打开

  1. RMAN> backup archivelog all not backed up;

  3. Starting backup at 12-MAR-16
  4. current log archived
  5. using channel ORA_DISK_1
  6. skipping archived logs of thread 1 from sequence 5 to 30; already backed up
  7. channel ORA_DISK_1: starting archived log backup set
  8. channel ORA_DISK_1: specifying archived log(s) in backup set
  9. input archived log thread=1 sequence=31 RECID=27 STAMP=906292476
  10. channel ORA_DISK_1: starting piece 1 at 12-MAR-16
  11. channel ORA_DISK_1: finished piece 1 at 12-MAR-16
  12. piece handle=/u01/app/oracle/fast_recovery_area/ORCL/backupset/2016_03_12/o1_mf_annnn_TAG20160312T115436_cg74qwtq_.bkp tag=TAG20160312T115436 comment=NONE
  13. channel ORA_DISK_1: backup set complete, elapsed time: 00:00:01
  14. Finished backup at 12-MAR-16
可以看到，除了新产生的31号归档，前面的归档日志均已跳过备份。

将命令稍微修改一下

  1. RMAN> backup archivelog all not backed up 2 times;

  3. Starting backup at 12-MAR-16
  4. current log archived
  5. using channel ORA_DISK_1
  6. channel ORA_DISK_1: starting archived log backup set
  7. channel ORA_DISK_1: specifying archived log(s) in backup set

  22. input archived log thread=1 sequence=19 RECID=15 STAMP=906275691
  23. input archived log thread=1 sequence=20 RECID=16 STAMP=906275730
  24. input archived log thread=1 sequence=21 RECID=17 STAMP=906275892
  25. input archived log thread=1 sequence=22 RECID=18 STAMP=906285113
  26. input archived log thread=1 sequence=23 RECID=19 STAMP=906285372
  27. input archived log thread=1 sequence=24 RECID=20 STAMP=906287723
  28. input archived log thread=1 sequence=25 RECID=21 STAMP=906289627
  29. input archived log thread=1 sequence=26 RECID=22 STAMP=906291279
  30. input archived log thread=1 sequence=27 RECID=23 STAMP=906291412
  31. input archived log thread=1 sequence=28 RECID=24 STAMP=906291557
  32. input archived log thread=1 sequence=29 RECID=25 STAMP=906291740
  33. input archived log thread=1 sequence=30 RECID=26 STAMP=906292245
  34. input archived log thread=1 sequence=31 RECID=27 STAMP=906292476
  35. input archived log thread=1 sequence=32 RECID=28 STAMP=906292679
  36. channel ORA_DISK_1: starting piece 1 at 12-MAR-16
  37. channel ORA_DISK_1: finished piece 1 at 12-MAR-16
  38. piece handle=/u01/app/oracle/fast_recovery_area/ORCL/backupset/2016_03_12/o1_mf_annnn_TAG20160312T115759_cg74y7vy_.bkp tag=TAG20160312T115759 comment=NONE
  39. channel ORA_DISK_1: backup set complete, elapsed time: 00:00:15
  40. 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

点击(此处)折叠或打开

  1. RMAN> backup archivelog all not backed up 1 times;

  3. Starting backup at 12-MAR-16
  4. current log archived
  5. using channel ORA_DISK_1
  6. skipping archived logs of thread 1 from sequence 5 to 32; already backed up
  7. channel ORA_DISK_1: starting archived log backup set
  8. channel ORA_DISK_1: specifying archived log(s) in backup set
  9. input archived log thread=1 sequence=33 RECID=29 STAMP=906292883
  10. channel ORA_DISK_1: starting piece 1 at 12-MAR-16
  11. channel ORA_DISK_1: finished piece 1 at 12-MAR-16
  12. piece handle=/u01/app/oracle/fast_recovery_area/ORCL/backupset/2016_03_12/o1_mf_annnn_TAG20160312T120123_cg754mrr_.bkp tag=TAG20160312T120123 comment=NONE
  13. channel ORA_DISK_1: backup set complete, elapsed time: 00:00:01
  14. 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。
