一：数据备份mongodump

可以用mongodump 来做MongoDB 的库或表级别的备份，下面举例说明:

备份my_mongodb 数据库

[root@localhost bin]# ./mongodump -d my_mongodb
connected to: 127.0.0.1
DATABASE: my_mongodb to dump/my_mongodb
my_mongodb.system.indexes to dump/my_mongodb/system.indexes.bson
1 objects
my_mongodb.user to dump/my_mongodb/user.bson
2 objects
[root@localhost bin]# ll
总计 67648
-rwxr-xr-x 1 root root 7508756 2011-04-06 bsondump
drwxr-xr-x 3 root root 4096 04-10 23:54 dump
-rwxr-xr-x 1 root root 2978016 2011-04-06 mongo

此时会在当前目录下创建一个dump 目录，用于存放备份出来的文件

也可以指定备份存放的目录，

[root@localhost bin]# ./mongodump -d my_mongodb -o my_mongodb_dump
connected to: 127.0.0.1
DATABASE: my_mongodb to my_mongodb_dump/my_mongodb
my_mongodb.system.indexes to
my_mongodb_dump/my_mongodb/system.indexes.bson
1 objects
my_mongodb.user to my_mongodb_dump/my_mongodb/user.bson
2 objects
[root@localhost bin]#

二：数据恢复mongorestore

由于刚刚已经做了备份，所以我们先将库my_mongodb 删除掉

> use my_mongodb
switched to db my_mongodb
> db.dropDatabase()
{ "dropped" : "my_mongodb", "ok" : 1 }
> show dbs
admin (empty)
local (empty)
test (empty)
>

接下来我们进行数据库恢复

[root@localhost bin]# ./mongorestore -d my_mongodb my_mongodb_dump/*
connected to: 127.0.0.1
Wed Apr 11 00:03:03 my_mongodb_dump/my_mongodb/user.bson
Wed Apr 11 00:03:03 going into namespace [my_mongodb.user]
Wed Apr 11 00:03:03 2 objects found
Wed Apr 11 00:03:03 my_mongodb_dump/my_mongodb/system.indexes.bson
Wed Apr 11 00:03:03 going into namespace [my_mongodb.system.indexes]
Wed Apr 11 00:03:03 { name: "_id_", ns: "my_mongodb.user", key: { _id: 1 }, v: 0 }
Wed Apr 11 00:03:03 1 objects found
[root@localhost bin]#

经验证数据库又回来了，其实要是想恢复库，也大可不必先删除my_mongodb 库，只要指

明 –drop 参数，就可以在恢复的时候先删除表然后再向表中插入数据的
