  • backup archivelog all not backed up

    backup archivelog all not backed up;
    这条命令可以用来备份没有备份过的归档日志，同时不会备份已经备份过的归档日志。下面是具体用法。

    第一次备份归档日志

    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. 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=5 RECID=1 STAMP=906200876
    9. input archived log thread=1 sequence=6 RECID=2 STAMP=906275330

    12. input archived log thread=1 sequence=9 RECID=5 STAMP=906275493
    13. input archived log thread=1 sequence=10 RECID=6 STAMP=906275503
    14. input archived log thread=1 sequence=11 RECID=7 STAMP=906275511
    15. input archived log thread=1 sequence=12 RECID=8 STAMP=906275530
    16. input archived log thread=1 sequence=13 RECID=9 STAMP=906275556
    17. input archived log thread=1 sequence=14 RECID=10 STAMP=906275574
    18. input archived log thread=1 sequence=15 RECID=11 STAMP=906275592
    19. input archived log thread=1 sequence=16 RECID=12 STAMP=906275612
    20. input archived log thread=1 sequence=17 RECID=13 STAMP=906275634
    21. input archived log thread=1 sequence=18 RECID=14 STAMP=906275673
    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. channel ORA_DISK_1: starting piece 1 at 12-MAR-16
    35. channel ORA_DISK_1: finished piece 1 at 12-MAR-16
    36. piece handle=/u01/app/oracle/fast_recovery_area/ORCL/backupset/2016_03_12/o1_mf_annnn_TAG20160312T115045_cg74jop2_.bkp tag=TAG20160312T115045 comment=NONE
    37. channel ORA_DISK_1: backup set complete, elapsed time: 00:00:15
    38. Finished backup at 12-MAR-16


    第二次备份归档日志

    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
    8. input archived log thread=1 sequence=5 RECID=1 STAMP=906200876
    9. input archived log thread=1 sequence=6 RECID=2 STAMP=906275330
    10. input archived log thread=1 sequence=7 RECID=3 STAMP=906275462
    11. input archived log thread=1 sequence=8 RECID=4 STAMP=906275486
    12. input archived log thread=1 sequence=9 RECID=5 STAMP=906275493
    13. input archived log thread=1 sequence=10 RECID=6 STAMP=906275503
    14. input archived log thread=1 sequence=11 RECID=7 STAMP=906275511
    15. input archived log thread=1 sequence=12 RECID=8 STAMP=906275530
    16. input archived log thread=1 sequence=13 RECID=9 STAMP=906275556
    17. input archived log thread=1 sequence=14 RECID=10 STAMP=906275574
    18. input archived log thread=1 sequence=15 RECID=11 STAMP=906275592
    19. input archived log thread=1 sequence=16 RECID=12 STAMP=906275612
    20. input archived log thread=1 sequence=17 RECID=13 STAMP=906275634
    21. input archived log thread=1 sequence=18 RECID=14 STAMP=906275673
    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

    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备份，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。
