Mongodump getting blank folders

Question

I am trying to run this command from a remote ssh

mongodump --host mongodb1.example.net --port 27017 --username user --password pass --out /opt/backup/mongodump-2013-10-24

However, all I am getting is blank folders for each collections.

What am I doing wrong?

Info (if it matters): Source Mongodb is on Windows Server And SSH is of a remote Ubuntu Machine

Here is the terminal output:

connected to: ip.ip.ip.ip:27017
Thu Feb 18 00:46:01.757 all dbs
Thu Feb 18 00:46:01.809 DATABASE: admin  to     /opt/backup/mongodump-2013-10-24/admin
Thu Feb 18 00:46:01.903 DATABASE: anthony_data       to     /opt/backup/mongodump-2013-10-24/anthony_data
Thu Feb 18 00:46:02.004 DATABASE: temp_data  to     /opt/backup/mongodump-2013-10-24/temp_data
Thu Feb 18 00:46:02.104 DATABASE: zoomy   to     /opt/backup/mongodump-2013-10-24/zoomy

So it creates empty folder for all collections. But there is no bson in it

Answer 1

Check that your copy of mongodump and the database itself is the same version.

I had the exact same problem (complete with no terminal output or logs) when I tried to do a dump of a mongo 3.2.4 server with a 2.4.1 mongodump client. Removing the older client and installing the newer one resolved it immediately.

Answer 2

I was using the default mongodb-client deb package with Ubuntu. I removed those and installed the mongodb-org-tools package from mongodb.com https://docs.mongodb.com/master/tutorial/install-mongodb-on-ubuntu/?_ga=2.36209632.1945690590.1499275806-1594815486.1499275806

They have other install instructions for your specific OS if you are not on Ubuntu https://www.mongodb.com/download-center?jmp=nav#community
