I want to copy from one mongo db to another db on the same server. Mongo version is 2.6.3 on Win 2008 64bit.
I ran the command:
mongo localhost:27017/admin -u <> -p <> --eval "db.copyDatabase('db_master','db_copy1')"
This worked and created db_copy1 with all the users in it. I did db.getUsers() on db_copy1 and it returned all users. All was fine.
Then I went on to copy the database db_copy1 to db_copy2 using the same command above (with different database names obviously). But the resultant db_copy2 had no users in it.
Fairly new to mongo, so quite possible I have missed something.
Thanks in advance for all your help!

One of the things I love about Mongodb is that rather than mess about with commands like that you can just copy the files.
Just go to the directory with the data files in it and copy them to the dbpath for your new database. If you don't want a certain database, don't copy the files with that database name!

I am on Linux Server. My MongoDB Database is stored there. Now if I want to delete the database from another machine lets say my development machine, then for that I created the steps but not working for me.
create a delete.sh file
#!usr/bin/env mongo
#instance Ip assume:
mongo 12.122.12.12:27017/tempDatabase --eval "db.dropDatabase"
But I am unable to delete the Database. Any idea that where I have done mistakes. Any interaction is really appreciated
I am new in Meteorjs and i am using mongo db which comes with the meteor package.
I have made one small meteor application using mongodb and now i want to take backup of the mongo db database. I have seen many web sites and still i am not able to backup my data base. Everyone explained the same thing that in mongo db folder use mongodump and mongostore but when i use mongodump and mongostore on my terminal then it displays something like 'mongodump' is not an internal or external source command. Can u please help me in finding out the solution.
I have found that the easiest way to backup your database (or move it between meteor installations for that matter) is to simple copy the files in .meteor\local\db
Then you don't have to worry about all that mongodb dump stuff. Simple.
I am going to be doing some major DB restructuring in MongoDB that converts a bunch of records. I've ran this script against a copied DB locally and it works fine, so it should also work on the production database.
Is there an easy way of copying a DB instance into a new DB? I figured I could shut down MongoDB and copy the files into a new directory, rename them to the new DB, and then move them into the MongoDB data directory.
It's usually pretty slow to copy large DB files like that, so I wondered if there was a Mongo-specific way of copying DB's.
In case it is sufficient to copy only some collections, you can copy them as follows without shutting down the db server:
http://xmlquerying.blogspot.de/2012/10/copying-data-between-mongo-databases.html
Otherwise use mongodump and mongorestore.
http://docs.mongodb.org/manual/tutorial/backup-databases-with-binary-database-dumps/
I have separate development and production MongoDB servers and I want to keep actual data in development server for sometime. What I should use for it: mongodump, mongoimport or something else?
Clarification: I want to copy data from production to development.
If it's a one time-thing
and you want fine control over parameters such as which collections to sync, you should use:
mongodump to dump bson files of your Production DB to your local machine
mongorestore to then, retrieve the dumped BSON files in your Local DB
Otherwise you should check out mongo-sync
It's a script I wrote for my self when I had to constantly copy my Local MongoDB database to and from my Production DB for a Project (I know it's stupid).
Once you put your DB details in config.yml, you can start syncing using two simple commands:
./mongo-sync push # Push DB to Remote
./mongo-sync pull # Pull DB to Local
If you use it inside some project, it's a good idea to add config.yml to .gitignore
You can use the db.copyDatabase(...) or db.cloneDatabase(...) commands:
http://www.mongodb.org/display/DOCS/Copy+Database+Commands
This is faster than mongodump / mongorestore because it skips creating the bson representation on disk.
When you want the dev database to look exactly like the production database, you can just copy the files. I am currently running a setup where I synchronize my MongoDB database between my desktop and my notebook with dropbox - even that works flawless.
I have a web service application built using NodeJS. I am using mongodb as database.
The whole thing is in another system(A) in the network. Now I need to copy all the data to the mongodb database in my system(B).
Can anyone tell me the whole procedure in detail, like even from where I should execute the commands also. I am a beginner and have very little knowledge about mongodb.
You can use the db.cloneDatabase() command for that (docs).
Start the mongo shell from the command line on the destination server by running: mongo
Identify the name of the database to copy: use name
Copy the database from the source server: db.cloneDatabase("1.2.3.4")
Use mongodump and mongorestore utility.
