从本地Mongodb数据库备份

Question

我正在使用“mongodb-backup”插件进行数据库备份。

数据库连接的URL链接：

var _dbConnectionURL = 'mongodb://uname:password@LocalIpAddress:port/databasename?authdb=admin'; 
mongoose.connect(_dbConnectionURL); 

此代码与mongodb的连接的NodeJS。它运作良好。

现在我试图把备份从的NodeJS

var backup = require('mongodb-backup'); 
backup({ 
    uri: _dbConnectionURL, 
    root: './Media/MongoDB_BK', 
    tar: 'sample.tar', 
    callback: function (err) { 
     if (err) { 
      console.error(err); 
     } else { 
      console.log('finish'); 
     } 
    }, 
}); 

错误：

Answer 1

尝试使用，而不是authdb

var _dbConnectionURL = 'mongodb://uname:password@LocalIpAddress:port/databasename?authsource=admin'; 

authsource或尝试在选项参数

设置authdb

backup({ 
    uri: _dbConnectionURL, 
    root: './Media/MongoDB_BK', 
    tar: 'sample.tar', 
    options: { 
     authSource: 'admin'  
    } 
});
