  12. { "_id" : ObjectId("5594f119a9a970e631c4c217"), "d" : 199 }
  13. > db.d.find().count();
  14. 11
  16. > db.d.drop();
  17. true
  19. [root@ser6-52 myTest]# mongorestore -u superuser -p 123456 --authenticationDatabase admin -d myTest -c d /backup/mongodb/myTest_d_bak_201507021701.bak/myTest/d.bson

  22. 2015-07-02T17:23:20.593+0800 going into namespace [myTest.d]
  23. 11 objects found
  24. 2015-07-02T17:23:20.594+0800 Creating index: { key: { _id: 1 }, name: "_id_", ns: "myTest.d" }
  27. > db.d.find().count();
  28. 11

2.2 恢复单个数据库

代码语言：javascript
复制
[root@ser6-52 myTest]# mongorestore -u  superuser -p 123456  --authenticationDatabase admin   /backup/mongodb/myTest_bak_201507021653.bak
connected to: 127.0.0.1
2015-07-02T17:41:00.378+0800 /backup/mongodb/myTest_bak_201507021653.bak/myTest/d.bson
2015-07-02T17:41:00.378+0800 	going into namespace [myTest.d]
Restoring to myTest.d without dropping. Restored data will be inserted without raising errors; check your server log
11 objects found
2015-07-02T17:41:00.378+0800 	Creating index: { key: { _id: 1 }, name: "_id_", ns: "myTest.d" }
2015-07-02T17:41:00.383+0800 /backup/mongodb/myTest_bak_201507021653.bak/myTest/c.bson
2015-07-02T17:41:00.383+0800 	going into namespace [myTest.c]
Restoring to myTest.c without dropping. Restored data will be inserted without raising errors; check your server log
2000 objects found
2015-07-02T17:41:00.390+0800 	Creating index: { key: { _id: 1 }, name: "_id_", ns: "myTest.c" }

--这里恢复数据库的时候没有指定-d 数据库名称，否则报错（我看网上有的指定了）。我的mongodb版本是2.6.9，也许是个bug吧。

2.3 恢复所有数据库

代码语言：javascript
复制

三：mysql与mongodb简单对比

3.1 对比描述

Mongodb:

mongorestore恢复的时候，默认不是恢复到备份时刻的状态。

如：

①：假如我备份后，新增了几条数据，用备份恢复后，那几条新增的数据还在。

②：如果备份后某条数据被update了，用备份恢复后，数据是update后的结果，不是备份时间点的数据（如原本name='dan',备份后，将dan更新成了nihao,恢复后，数据还是nihao)

估计是恢复时，遇到_id一样的值，就没有做任何处理。

Mysql:

mysqldump是先删表，再建表，插入数据的，默认就能恢复到备份时刻的状态。

3.2 示例

3.2.1 mongodb

--备份记录请参考1.3

D表备份的数据有：

代码语言：javascript
复制
  1. > db.d.find();
  2. { "_id" : ObjectId("5594f048a9a970e631c4c20c"), "d" : 0 }
  3. { "_id" : ObjectId("5594f048a9a970e631c4c20d"), "d" : 1 }
  4. { "_id" : ObjectId("5594f048a9a970e631c4c20e"), "d" : 2 }
  5. { "_id" : ObjectId("5594f048a9a970e631c4c20f"), "d" : 3 }
  6. { "_id" : ObjectId("5594f048a9a970e631c4c210"), "d" : 4 }
  7. { "_id" : ObjectId("5594f048a9a970e631c4c212"), "d" : 6 }
  8. { "_id" : ObjectId("5594f048a9a970e631c4c213"), "d" : 7 }
  9. { "_id" : ObjectId("5594f048a9a970e631c4c214"), "d" : 8 }
  10. { "_id" : ObjectId("5594f048a9a970e631c4c215"), "d" : 9 }
  11. { "_id" : ObjectId("5594f0bea9a970e631c4c216"), "d" : 99 }
  12. { "_id" : ObjectId("5594f119a9a970e631c4c217"), "d" : 199 }
  14. #在备份完成后插入一条数据：
  15. d表插入999999后的数据是：
  16. > db.d.find();
  17. { "_id" : ObjectId("5594f048a9a970e631c4c20c"), "d" : 0 }
  18. { "_id" : ObjectId("5594f048a9a970e631c4c20d"), "d" : 1 }
  19. { "_id" : ObjectId("5594f048a9a970e631c4c20e"), "d" : 2 }
  20. { "_id" : ObjectId("5594f048a9a970e631c4c20f"), "d" : 3 }
  21. { "_id" : ObjectId("5594f048a9a970e631c4c210"), "d" : 4 }
  22. { "_id" : ObjectId("5594f048a9a970e631c4c212"), "d" : 6 }
  23. { "_id" : ObjectId("5594f048a9a970e631c4c213"), "d" : 7 }
  24. { "_id" : ObjectId("5594f048a9a970e631c4c214"), "d" : 8 }
  25. { "_id" : ObjectId("5594f048a9a970e631c4c215"), "d" : 9 }
  26. { "_id" : ObjectId("5594f0bea9a970e631c4c216"), "d" : 99 }
  27. { "_id" : ObjectId("5594f119a9a970e631c4c217"), "d" : 199 }
  28. { "_id" : ObjectId("5595ffbcdeae2abeba569b24"), "d" : 999999 }
  30. #现在不删表进行恢复：
  32. [root@ser6-52 ~]# mongorestore -u superuser -p 123456 --authenticationDatabase admin -d myTest -c d /backup/mongodb/myTest_d_bak_201507021701.bak/myTest/d.bson
  33. connected to: 127.0.0.1

  35. 2015-07-03T11:41:49.188+0800 going into namespace [myTest.d]
  36. Restoring to myTest.d without dropping. Restored data will be inserted without raising errors; check your server log
  37. 11 objects found
  38. 2015-07-03T11:41:49.189+0800 Creating index: { key: { _id: 1 }, name: "_id_", ns: "myTest.d" }
  40. > db.d.find();
  41. { "_id" : ObjectId("5594f048a9a970e631c4c20c"), "d" : 0 }
  42. { "_id" : ObjectId("5594f048a9a970e631c4c20d"), "d" : 1 }
  43. { "_id" : ObjectId("5594f048a9a970e631c4c20e"), "d" : 2 }
  44. { "_id" : ObjectId("5594f048a9a970e631c4c20f"), "d" : 3 }
  45. { "_id" : ObjectId("5594f048a9a970e631c4c210"), "d" : 4 }
  46. { "_id" : ObjectId("5594f048a9a970e631c4c212"), "d" : 6 }
  47. { "_id" : ObjectId("5594f048a9a970e631c4c213"), "d" : 7 }
  48. { "_id" : ObjectId("5594f048a9a970e631c4c214"), "d" : 8 }
  49. { "_id" : ObjectId("5594f048a9a970e631c4c215"), "d" : 9 }
  50. { "_id" : ObjectId("5594f0bea9a970e631c4c216"), "d" : 99 }
  51. { "_id" : ObjectId("5594f119a9a970e631c4c217"), "d" : 199 }
  52. { "_id" : ObjectId("5595ffbcdeae2abeba569b24"), "d" : 999999 }
  53. > db.d.find().count();
  54. 12

恢复后999999依然存在，说明备份后新增的数据在恢复时不会被删除。

如果备份后某条数据被update了，恢复的时候，数据是怎样的呢？

#准备测试数据

{ "_id" : ObjectId("559627a7deae2abeba569b26"), "id" : "1", "name" : "dan", "age" : 25 }
{ "_id" : ObjectId("559627b4deae2abeba569b27"), "id" : "2", "name" : "jiaojiao", "age" : 25 }

恢复后结果仍然是jiaojiao,不是jiao,说明备份后倘若某条记录被更新了，默认无法恢复到备份点的状态。

这和mysqldump不同。mysql会恢复到备份点的状态。

恢复的时候加上--drop参数，就能将数据恢复到备份时刻的状态了。

#插入一条数据

mysql> insert into t1(id) values(3);

Query OK, 1 row affected (0.60 sec)

mysql> commit;

Query OK, 0 rows affected (0.00 sec)

#恢复

[root@ser6-51 mysql]# mysql -u root -p  dba < /backup/mysql/dba_t1_bak_201507031338.bak 

Enter password: 

mysql> select * from t1;

+------+

| id   |

+------+

|    1 |

|    2 |

+------+

2 rows in set (0.00 sec)

新插入的id为3的记录没有了。

此时，我删除其中一条数据：

mysql> delete from t1 where id = 1;

Query OK, 1 row affected (0.33 sec)

mysql> commit;

恢复：

[root@ser6-51 mysql]# mysql -u root -p  dba < /backup/mysql/dba_t1_bak_201507031338.bak 

Enter password: 

mysql> select * from t1;

+------+

| id   |

+------+

|    1 |

|    2 |

+------+

2 rows in set (0.04 sec)

因为Mysql就是先删表，再插入的，只能恢复到备份时刻那个点的状态。
