Problem Statement

In this post, we will learn how to take backup from MongoDB instance, and restore that to another MongoDB instance.

Tools Required

The tool you require are:
  • mongodump - To take backup

Taking Backup from a Running MongoDB instance

Run following command to take backup of a specific database ``` mongodump --db YOUR_DB_NAME --out YOUR_TARGET_FOLDER ```

This will take backup of your passed database name, to the passed folder. It will create a new folder under the path passed, and its name will be the name of your DB.

Run following command:

mongodump --host localhost:27020 --db YOUR_DB_NAME --out YOUR_TARGET_FOLDER

Run following command, if your instance is running on default port i.e. 27017:

If your MongoDB instance runs on another port

``` mongorestore --uri mongodb://localhost:27020 --db YOUR_DB_NAME YOUR_TARGET_FOLDER/YOUR_DB_NAME ```
