MongoDB 3.0.1 mongodump error

Question

I need to create a dumpfile of a MongoDB db using 'mongodump'.

    ubuntu-0864947@ubuntu-vm:~$ mongo
    MongoDB shell version: 3.0.1
    connecting to: test
    Server has startup warnings: 
    2015-03-30T14:26:08.806+0200 I CONTROL  [initandlisten] ** WARNING: You are running this process as the root user, which is not recommended.

    > mongodump

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

Can anyone please tell me what I am doing wrong here?

Thanks!

Answer 1

mongodump是与mongo mongodump的可执行文件，您需要在OS shell中而不是在MongoDB shell中执行它：

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

Answer 2

Just Go to bin Directory of Mongodb (mycase : c:\\mongodb\\bin) Then, Run : following Command mongodump --db database_name

Then go to Dump Directory Created inside Bin Folder

There you'll find folder of your named database and inside that .bson & .json file would be there just keep it safe .bson is your backup file
