Introduction

With MongoDB's mongodump and mongorestore commands, you can export and import data to your Mongo database.

Export Database

Go to your local Mongo bin folder. Type mongodump --db {your database name}.

This command will export all your database data as binary files under the dump folder. When I had 200 MB with a total collection of around 50,000 documents, this command ran in about 2–3 seconds on my Windows 8 (8GB memory) PC.

Restore Your Database to a Remote Connected Database

Assume your remote Mongo database has nothing and you just want to import everything you just exported from the local Mongo database. Run the following command:

mongorestore --db {your database} --host {server name} --port {server port number} --username {your database user name} --password {your database user's password} dump/{your database name}

Conclusion

MongoDB's mongodump and mongorestore commands provide a simple and fast way to export and import data between local and remote databases. These two commands are essential tools for database backup and migration.
