How to make a backup and restore in meteor.js? - mongodb

I want to create a backup and restore in Meteor.js, but I don't have any
solution to create a backup and restore MongoDB database with Meteor.js.
I need some Guide line to do this.

Restore datatabase : mongorestore --port --db .
backup/dump : mongoimport/mo

To connect to the Mongo database for your local (or inner) mongodb of meteor, enter in cmd (in the folder of your project):
meteor mongo

Restoring a mongo database but mongo shell does not show it

mongodump was used long time ago to create a backup, now in order to restore the database for a Meteor app, this command was used:
ais2> mongorestore C:\Users\AAA\Documents\meteor\apps\dump\dump\
PS C:\Users\empl1\Documents\meteor\apps\ais2> mongorestore C:\Users\AAA\Documents\meteor\apps\dump\dump\
preparing collections to restore from
reading metadata for dbais2.dataTeckAllMatchCol from C:\Users\AAA\Documents\meteor\apps\dump\dump\dbais2\dataTeckAllMatchCol.metadata.json
reading metadata for dbais2.makeModelCol from C:\Users\AAA\Documents\meteor\apps\dump\dump\dbais2\makeModelCol.metadata.json
reading metadata for dbais2.usageCol from C:\Users\AAA\Documents\meteor\apps\dump\dump\dbais2\usageCol.metadata.json
reading metadata for dbais2.vehiclesDetailsCol from C:\Users\AAA\Documents\meteor\apps\dump\dump\dbais2\vehiclesDetailsCol.metadata.json
restoring dbais2.dataTeckAllMatchCol from C:\Users\AAA\Documents\meteor\apps\dump\dump\dbais2\dataTeckAllMatchCol.bson
restoring dbais2.makeModelCol from C:\Users\AAA\Documents\meteor\apps\dump\dump\dbais2\makeModelCol.bson
restoring dbais2.usageCol from C:\Users\AAA\Documents\meteor\apps\dump\dump\dbais2\usageCol.bson
restoring dbais2.vehiclesDetailsCol from C:\Users\AAA\Documents\meteor\apps\dump\dump\dbais2\vehiclesDetailsCol.bson
finished restoring dbais2.dataTeckAllMatchCol (11705 documents, 0 failures)
Since I have a directory "dbais2" with all the database files located in the above path.
In a new shell ais2> meteor mongo opens a mongo shell, but show dbs does not show the "dbais2". How can I use the newly restored database? or it was not restored correctly? if so. how to restore it correctly?
Thanks
When you run mongorestore as is, it will connect to the mongo instance running on port 27017 on your local machine (if any). That's what you would use in production. Since the restore succeeded, it must be that you have such an instance running. In that case, run mongo ais2 to connect to that instance and db.
In development, meteor runs its own mongo instance on port 3001 (assuming you used meteor on the default port 3000). When you run meteor mongo that is the instance your shell will connect to. If you want to restore into that, then rerun your command with the port specified:
mongorestore --port=3001 -d meteor C:\Users\AAA\Documents\meteor\apps\dump\dump\
After that you should see your data in the shell opened by meteor mongo. Note that in this command I'm also overriding the database name, so that the data will be imported into the database used by meteor in development (also called meteor).

How to clone a collection from one MongoDB to another on same server

I'm using Mongo 3.2. I have two databases on my localhost named client1 and client2.
Now client1 contains a collection named users.
I want to clone this collection to client2.
I have tried:-
use client2
db.cloneCollection('localhost:27017', 'client1.users',
{ 'active' : true } )
This outputs
{
"ok" : 0.0,
"errmsg" : "can't cloneCollection from self"
}
Is cloning a collection from one db to another on the same server prohibited?
Few things :
In general cloneCollection is used for different mongo instances but not to copy on same instances.
Also if you're using v4.2 you should stop using copyDB & cloneCollection cause they're deprecated compatibility-with-v4.2 & start using mongodump and mongorestore or mongoexport & mongoimport.
I would suggest to use mongodump & mongorestore :
Cause mongodump would preserve MongoDB's data types i.e.; bson types.
mongodump creates a binary where as mongoexport would convert bson to json & again mongoimport will convert json to bson while writing, which is why they're slow. You can use mongoexport & mongoimport when you wanted to analyze your collections data visually or use json data for any other purpose.
You can run below script in shell
declare - a collections = ("collectionName1" "collectionName2")
for i in "${collections[#]}"
do
echo "$i"
mongodump --host "All-shards" --username=uname --password password --ssl --authenticationDatabase admin --db dbname --collection "$i"
mongorestore --host=host-shard-name --port=27017 --username=uname --password=psswrd --ssl --authenticationDatabase=admin --db=dbname --collection= "$i" ./dump/dbName/"$i".bson;
done
To use mongodump, you must run mongodump against a running mongod or mongos instance. So these commands are being run expecting mongo is properly installed & path setup is good, if not you can navigate to mongo folder & run like ./mongodump & ./mongorestore. Above script will be useful if you wanted to backup multiple collections, You need specify few things in script like :
mongodump--host "All-shards" -> Here you need to specify all shards if your MongoDB is a replica set, if not you can specify localhost:27017.
mongorestore --host=host-shard-name -> You've to specify one shard of replica set, else your localhost, Few things here can be optional --ssl, --username, --password.
So mongodump will create a folder named dump for first time which will have the sub-folders with dbNames & each sub-folder will has bson files respective to their collection names dumped, So you need to refer dbName in restore command & collection name will be taken from variable i -> ./dump/dbName/"$i".bson
Note : MongoDB v3.2 is so old & in cloud based MongoDB service Mongo-atlas it has already reached it's end of lifecycle, So please upgrade asap. If you're looking for a free mongo instance or starting with MongoDB - you can try atlas.
db.cloneCollection() copies data directly between MongoDB instances.
https://docs.mongodb.com/v3.2/reference/method/db.cloneCollection/
That means you cannot clone inside the same mongod instance. Use mongoexport and mongoimport to clone your collection.
Since 4.2 MongoDb introduces $merge operator which allows copy from db1.collection to db2.collection.

Import Mongo Database to local meteor application

I've downloaded a backup of a Mongo database from a production application I have hosted on Mlab.com
I want to import that database to my local meteor application so I can test some changes to the architecture of the collections on the real application data without breaking the production app.
Is there a way to do this?
Much appreciated
You will need to install Mongo locally on your machine to get the utilities you need, which is basically mongorestore. The command will look something like this:
sudo mongorestore --db newdb --drop /var/backups/mongobackups/01-20-16/newdb/
Meteor can connect to your database using this environment variable:
MONGO_URL=mongo://localhost:27017/newdb
There is an article about it for more detail here: https://www.digitalocean.com/community/tutorials/how-to-back-up-restore-and-migrate-a-mongodb-database-on-ubuntu-14-04

How to dump (backup) several tables (collection) and recover from MongoDB?

I'm new in MongoDB and my english is too bad - so, i can't understand mongodb documentation.
I have to dump (backup) several tables (collection) from MongoDB base - how I can do it?
Which utility I have to use for recover collections from backup?
Thank you for your attention for my question!
Start your mongod server. Assuming that your mongod server is running on localhost and port 27017. Now open a command prompt and go to bin directory of your mongodb instance and type the command:
mongodump
This command will back all data of the server to directory /bin/dump/
To backup only specific collection, use:
mongodump --collection YOUR_COLLECTION_NAME --db YOUR_DB_NAME
On a good-bye note, to restore/recover data use command:
mongorestore

How to backup Backup mongo db in meteorjs as mongodump is not working

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.
