God knows why exactly you are getting this error. But make sure you are having mongod running in background. Though it has nothing to with this error. By the way did you manually changed the dump files? – Happily 21/9, 2013 at 10:55

No I downloaded the assignment dump file. and extracted it.If you have done earlier can you please give me steps. – Hagiographa 21/9, 2013 at 10:59

Are you doing that mongodb 101 course? I also did that, it worked for me. I hope you have the binaries of mongorestore of a stable mongodb release. – Happily 21/9, 2013 at 11:3

yes, I am doing the same. might me I am going it in wrong way. could you please give me way, where to put dump.bson. my db path is dbpath=C:\mongodb\data\db\ – Hagiographa 21/9, 2013 at 11:8

Actually I use Mac OS X. Really don't know much about Windows. Try following the instructions they give for windows. Or better discuss at their course forum. Many might have faced similar problem. Tension not, ho jayega :) – Happily 21/9, 2013 at 11:16

@SandeepSingh Suggestion - Its always good to accept an answer. People looking for a solution to the same problem can just see that right up as the first answer. – Clere 4/4, 2020 at 6:10

@Clere - Yes you are correct, certainly I missed to accept the right answer as there was not any answer when I posted it. Now it will very unfair for others, if I am going to accept any answer from this. :) – Hagiographa 7/4, 2020 at 12:21

@SandeepSingh you can always choose what is the most reasonably explained and useful answer according to you. (despite the votes) ..breaking a tie could also happen using the time when the answer was posted. <= opinions – Clere 7/4, 2020 at 12:25

mongodump: To dump all the records:

mongodump --db databasename

To limit the amount of data included in the database dump, you can specify --db and --collection as options to mongodump. For example:

mongodump --collection myCollection --db test

This operation creates a dump of the collection named myCollection from the database 'test' in a dump/ subdirectory of the current working directory. NOTE: mongodump overwrites output files if they exist in the backup data folder.

mongorestore: To restore all data to the original database:

1) mongorestore --verbose \path\dump

or restore to a new database:

2) mongorestore --db databasename --verbose \path\dump\<dumpfolder>

Note: Both requires mongod instances.

How to pass the DB credentials when restoring? – Recoverable 15/7, 2018 at 3:42

@Recoverable mongorestore -u <username> --authenticationDatabase "admin" --db databasename. Authentication database not necessarily 'admin', but probably. You should be asked for the password interactively (you may also need to elevate with sudo). – Atelectasis 15/10, 2018 at 19:57

it should be --db or -d but not -db – Circumambulate 21/10, 2020 at 3:51

Dump DB by mongodump

mongodump --host <database-host> -d <database-name> --port <database-port> --out directory

Restore DB by mongorestore

With Index Restore

mongorestore --host <database-host> -d <database-name> --port <database-port> foldername

Without Index Restore

mongorestore --noIndexRestore --host <database-host> -d <database-name> --port <database-port> foldername

Import Single Collection from CSV [1st row will be used as Col/Key Name]

mongoimport --db <database-name> --port <database-port> --collection <collection-name> --type csv --headerline --file /path/to/myfile.csv

Import Single Collection from JSON

mongoimport --db <database-name> --port <database-port> --collection <collection-name> --file input.json

To restore a single database:

Backup the testdb database
```
$ mongodump --db testdb
```
Restore the testdb database to a new database called testdb2
```
$ mongorestore --db testdb2 dump/testdb
```

To restore all databases:

Backup all databases
```
$ mongodump
```
Restore all databases
```
$ mongorestore dump
```

The directory should be named 'dump' and this directory should have a directory which contains the .bson and .json files. This directory should be named as your db name.

eg: if your db name is institution then the second directory name should be institution.

After this step, go the directory enclosing the dump folder in the terminal, and run the command

mongorestore --drop.

Do see to it that mongo is up and running.

This should work fine.

You should be sure before you use --drop in your command cause it will drop the existing collection in the DB and recreate a new collection with the data from the dump file, technically you will loose all the current data(which is not in dump file) from DB in mongo instance..!!! – Ileana 25/6, 2019 at 5:39

Follow this path.

C:\Program Files\MongoDB\Server\4.2\bin

Run the cmd in bin folder and paste the below command

mongorestore --db <name-your-database-want-to-restore-as> <path-of-dumped-database>

For Example:

mongorestore --db testDb D:\Documents\Dump\myDb

You can take a dump to your local machine using this command:

mongodump -h <host>:<port> -u <username> -p <password> -d ubertower-new -o /path/to/destination/directory

You can restore from the local machine to your Mongo DB using this command

mongorestore -h <host>:<port> -u <username> -p <password> -d <DBNAME> /path/to/destination/directory/<DBNAME>

Start mongod
Navigate to folder where you have extracted "enron.zip" in OS shell(cmd in case of windows)
Then type ">mongorestore -d your_db_name dump/enron"

For mongoDB database restore use this command here

mongorestore --db databasename --drop <dump/file/path>

If you are okay to drop the existing collections then then following command works fine for me.

Okay to drop the existing collections

$ uri_complete="your_complete_uri"
$ restoreFileName="your_restore_filename"
$ mongorestore --uri=$uri_complete -v --gzip --archive=$restoreFileName --drop

Not okay to drop existing collections

$ uri_complete="your_complete_uri"
$ restoreFileName="your_restore_filename"
$ mongorestore --uri=$uri_complete -v --gzip --archive=$restoreFileName

If your database is running on localhost on default port without authentication then the following will work.

$ mongorestore -v --gzip --archive=restorefile.gzip --drop

More details - mongorestore

You can also restore your downloaded Atlas Backup .wt WiredTiger files (which unzips or untar as a restore folder) to your local MongoDB.

First, make a backup of your /data/db path. Call it /data_20200407/db. Second, copy paste all the .wt files from your Atlas Backup restore folder into your local /data/db path. Restart your Ubuntu or MongoDB server. Start your Mongo shell and you should have those restored files there.

I have been through a lot of trouble so I came up with my own solution, I created this script, just set the path inside script and db name and run it, it will do the trick

#!/bin/bash

FILES= #absolute or relative path to dump directory
DB=`db` #db name
for file in $FILES
do

    name=$(basename $file)
    collection="${name%.*}"
    echo `mongoimport --db "$DB" --file "$name" --collection "$collection"`

done
