Guys I am trying to backup a database.
First I connect to the server using a ssh tunel, then I execute the following command:
mongodump -d mydatabase -o ~/myfolder
and I get this message:
connected to: 127.0.0.1 Thu Feb 6 18:00:56 DATABASE: mydatabase to
/home/backups/myfolder/myfolder
As you can see, the mongodump is creating a folder inside a folder, but inside this folder I don't have any files, no json, no bson file.
Could someone, explain me how to make a backup on my server using ssh and the move the files to my local machine.
Thanks in advance.
this is the command you are looking for.
this command will access your server database locally
4321 is a port number which can be any port number in which you run your mongodb server root#144.154.22.11 and this is your server ip.
ssh -L 4321:localhost:27017 root#144.154.22.11 -f -N
and after this
mongodump --port 4321
this command will make your mongodb dump.

I have provided ACCESS FROM ANYWHERE IP details in network access tab too. In that case, there should not be any issues while connecting. I have installed home-brew in my MacOS and installed mongodb database tools, since my terminal didn't recognise mongoexport command initially. Please let me know if I'm missing any detail in connection string.

If you want to take a backup from a remote database and restore it on your local machine.
Get your local machine IP by opening the terminal and running this command dig +short myip.opendns.com #resolver1.opendns.com
Add your machine IP address in the mongo atlas and provide access for this IP to limited hours only. In-network access tab.
Run this command mongodump --uri 'PUT_DB_HERE_URI' --out $(pwd) which takes a backup from your remote db you will find collection files with extension .bson.
To restore this data in your local database run this command mongorestore --host 127.0.0.1 --port 27017 -d database_name ./exported_folder_which_contains_.bson files/ .

I had the same issue with mongorestore and turns out it was just a mongorestore version problem, just updgraded it and everything works fine now
We have a remote MongoDB server and we have mongodump data on a local developer's machine. What is the best way to restore the remote MongoDB server data with the local data? Is there a mongo command that we can use?
Alright so we did this in two steps. I think you can do it in one step, with just mongorestore.
First we moved the data from the local machine to the remote machine with the scp command:
scp <path-to-mongofile> <remote-host>:<absolute-file-path>
then we ssh'd into the remote mongod server, and used mongorestore to restore the db
mongorestore --host=$HOST --port=$PORT -u $ADMIN_USER -p $PSWD --db <your-db> <absolute-path-to-restore-db> --authenticationDatabase "admin"
but I think the first scp command is redundant. In fact, if you cannot ssh into the server running mongod, then you will have to use the mongorestore command directly from the local developer's machine.
Just use mongorestore but point it towards the remote server, such as:
$ mongorestore -h ds01234567.mlab.com:12345 -d heroku_fj33kf -u <user> -p <password> <input db directory>
From MongoLab's docs
I am trying to take a mongodb dump from amazon aws server.
Kinldy share the command
From Local it is working
sudo mongodump -d db** -o /opt/backup/
How to do it from server
sudo mongodump -d db** -i /opt/x.pem ubuntu#ip:/
There are three things you need to do in order to make sure remote mongodump is possible -
Make sure the security group allows for communications between your
computer and port 27017 (or any other port mongo is running on your
server)
Check if mongodb is configured to bind a specific IP (by default it
is binded to 127.0.0.1 which allows for local communications only)
Change your mongodump command to something like this - mongodump
-d <db**> -u <username> -p <password> --host <server_ip/dns>
Having said that, it is often better to ssh into the server and dump the data locally, then zip it and copy it to your local machine in order to minimize network load. If you have ssh access to the server this would be a much better (and more secure) approach for dumping your data.
I would like to read data from remote mongo database server. I tried by below ways.
ssh username#hostname
"mongo databaseName --eval 'db.collection.find({\"params1\":\"2\",\"params2\":\"2\"})'"
or
ssh username#hostname
"mongo databaseName --eval 'printjson(db.collection.find({\"params1\":\"2\", \"params2\":\"2\"}))'"
I used both ways, but I can't get the correct result output from database server.
How should I do ?
The following format should work, note that I specifically included the full path of the mongo executable on the remote database server. If this command does not work, you should ensure that SSH is running on the server and check to see if there is any authentication settings on your database.
ssh username#hostname "/usr/local/mongodb/bin/mongo --norc --eval 'db.collection.find().forEach(printjson)'"
I have a MongoDB database that resides on a remote server machine whose IP address is 192.168.1.20 on a local network. For development and testing purposes, and since I am not allowed to modify or delete the database on the server for security purposes, I want to copy the database on my local machine for my personal use.
Can anyone please tell me, how do I achieve this?
I do this by creating a dump of the remote db to my local machine, which I then restore:
Make sure you have a mongo instance up and running (eg. run mongod.exe from your bin folder in a terminal window. On my windows computer that's C:\mongodb\bin)
Make a dump from remote db: Open a new terminal window, move to the bin folder again, run:
mongodump -h example.host.com --port 21018 -d dbname --username username --password yourpass
(Change the parameters to suit your own situation.)
Restore the dumped database: Once the dump has been made, run the following command so that you have a local db:
mongorestore -d theNameYouWantForYourLocalDB dump\nameOfRemoteDB
(replace nameOfRemoteDB with the name of the remote db, the same as in previous command, and replace theNameYouWantForYourLocalDB with the name that you want your new local db to have)
There is copy database command which I guess should be good fit for your need.
db.copyDatabase("DATABASENAME", "DATABASENAME", "localhost:27018");
Alternatively, you can just stop MongoDb, copy the database files to another server and run an instance of MongoDb there.
EDIT 2020-04-25
Quote from MongoDB documentation
MongoDB 4.0 deprecates the copydb and the clone commands and their mongo shell helpers db.copyDatabase() and db.cloneDatabase().
As alternatives, users can use mongodump and mongorestore (with the mongorestore options --nsFrom and --nsTo) or write a script using the drivers.

This should be a comment to the answer of #malla, but I don't have enough reputation to comment so I'm posting it here for other's reference.
In step 2, When you are trying to dump file from a remote server, remember to add out option so that you can restore locally later: (in my first try, I didn't add it and it failed, saying dump\db_name was not found).I'm not sure whether my way efficient or not. But it worked for me.
Step 2:
mongodump -h example.host.com --port 21018 -d dbname --username username --password yourpass --out <path_you_want_to_dump>
Step 3:
mongorestore -d theNameYouWantForYourLocalDB \<path_you_want_to_dump> + nameOfRemoteDB
The mongoexport command:
http://docs.mongodb.org/manual/core/import-export/
Or, mongodump command:
http://docs.mongodb.org/manual/reference/program/mongodump/
mongodb has commandline tools for importing and exporting. Take a look at mongodump --collection collection --db test and mongorestore --collection people --db accounts dump/accounts/
http://docs.mongodb.org/v2.2/reference/mongodump/
http://docs.mongodb.org/v2.2/reference/mongorestore/
this even works over the network
You can use the mongoexport command to copy the database to your local machine.
