MongoDB 3.0.1 mongodump错误

Question

我需要使用 'mongodump'.

创建 MongoDB 数据库的转储文件

    ubuntu-0864947@ubuntu-vm:~$ mongo
    MongoDB shell version: 3.0.1
    connecting to: test
    Server has startup warnings:

    > mongodump RotterdamHaven
    2015-04-30T16:26:13.742+0200 E QUERY    SyntaxError: Unexpected identifier

谁能告诉我我做错了什么？

谢谢！

Answer 1

mongodump是一个类似mongo的可执行文件，你需要在OSshell中执行，而不是在MongoDB[=17=中执行]:

ubuntu-0864947@ubuntu-vm:~$ mongodump <arguments>

Answer 2

只需转到 Mongodb 的 bin 目录 (mycase : c:\mongodb\bin) 然后，运行 : 以下命令 mongodump --db database_name

然后转到在 Bin 文件夹中创建的转储目录

在那里你会找到你命名的数据库的文件夹 .bson & .json 文件会在那里只是保证它的安全。bson 是你的备份文件
