Question

在dump / enron目录中，messages.bson和messages.medata.json fiels。它应该恢复 120,477份文件。我想从中恢复数据。我输入命令：

mongorestore -v --db enron --drop  dump/enron

命令完成后，我收到一条消息：找到120477个物件不知道如何处理文件[dump / enron / messages.metadata.json]

但是在收集信息中，我看到112196文件使用：

db.messages.count()

你能告诉我它有什么问题吗？命令的输出：

消息是什么：“不知道如何处理文件[dump / enron / messages.metadata.json]”是什么意思？

Answer 2

恢复bson文件时需要指定数据库和集合。

它对我有用：

$ mongodump -d mark --collection coll 
connected to: 127.0.0.1
DATABASE: mark   to     dump/mark
    mark.coll to dump/mark/coll.bson
         1000 objects

和

  $ mongorestore -d mark --collection newcoll dump/mark/
    connected to: 127.0.0.1
    Wed Aug 29 11:48:39 dump/mark/coll.bson
    Wed Aug 29 11:48:39      going into namespace [mark.newcoll]
    1000 objects found

你可以尝试 -

mongorestore -d enron --collection messages /dump/enron/

mongodb恢复似乎没有恢复所有文件
