任何数据库都需要备份和恢复,,这个重要性就不多说了,大家都懂的。

MongoDB也提供了备份和恢复的功能,分别是MongoDB下载目录下的mongdump.exe和mongorestore.exe文件。

首先说下语法:

备份:

>mongodump -h dbhost -d dbname -o dbdirectory

-h:MongDB所在服务器地址,例如:127.0.0.1,当然也可以指定端口号:127.0.0.1:27017

-d:需要备份的数据库实例,例如:test

-o:备份的数据存放位置,例如:c:\data\dump,当然该目录需要提前建立,在备份完成后,系统自动在dump目录下建立一个test目录,这个目录里面存放该数据库实例的备份数据。

实例:>mongodump -h 127.0.0.1 -d test -o c:\data\dump\

 

恢复:

>mongorestore -h dbhost -d dbname --directoryperdb dbdirectory

-h:MongoDB所在服务器地址

-d:需要恢复的数据库实例,例如:test,当然这个名称也可以和备份时候的不一样,比如test2

--directoryperdb:备份数据所在位置,例如:c:\data\dump\test,这里为什么要多加一个test,而不是备份时候的dump,读者自己查看提示吧!

--drop:恢复的时候,先删除当前数据,然后恢复备份的数据。就是说,恢复后,备份后添加修改的数据都会被删除,谨慎使用!

实例:>mongorestore -h 127.0.0.1 -d test --directoryperdb c:\data\dump\test
