I created a backup of all my databases using mongodump command. Now I want to restore a specific database using mongorestore command.

How is this possible, I use this command: --db option then mongodb doesn't restore a specific database.


To restore a single database you need to provide the path to the dump directory as part of the mongorestore command line.

For example:

# Backup the training database
mongodump --db training

# Restore the training database to a new database called training2
mongorestore --db training2 dump/training

The --db option for mongodump specifies the source database to dump.

The --db option for mongorestore specifies the target database to restore into.

  • I backup using mongodump --archive to create .gz file. May I know how we restore from .gz file and also specify new database name? My .gz file size is 2Gb, so extracting it is very time-consuming. – Nam G VU Nov 2 '17 at 3:05
  • @NamGVU Can you post a new question including your version of mongodump and the exact command line you are using? The --archive command creates a special archive format which is different from --gzip. Depending on your mongodump version and command-line options used, there are different recommendations for renaming databases or collections with mongorestore. – Stennie Nov 2 '17 at 6:57

Use the following command to restore mongo db:

mongorestore -d dbname dbpath
$ mongorestore --drop -d <database-name> <dir-of-backup-files>
  • --drop Drop is necessary if you are replacing an existing db
  • -d <database-name> The name of the database to create/replace
  • <dir-of-backup-files> For some reason this is necessary even if it's the current directory

    this worked for me - just be careful as it will drop the db – Alexander Mills Sep 1 '17 at 20:56

Restoring using mongorestore

After making sure that mongod and mongo are running, go to the dump's parent directory in a new terminal. And use the command mongorestore dump. Where dump is the folder name in which the database dump is present.
