For standalone or a replica set, mongodump can be a part of a backup strategy with mongorestore for partial backups based on a query, syncing from production to staging or development environments, or changing the storage engine of a standalone. For an overview of mongodump in conjunction with mongorestore part of a backup and recovery strategy, see:. For 4. Run mongodump from the system command line, not the mongo shell.

To connect to a local MongoDB instance running on port and use the default settings to export the content, run mongodump without any command-line options:. Specify the hostname and port in the qatar companies directory connection string :. Specify the hostname and port in the --host :. Specify the hostname and port in the --host and --port :.

For more information on the options available, see Options. Specify the replica set name and members in the --uri connection string :. Specify the replica set name and members in the --host :. By default, mongodump reads from the primary of the replica set.

To override the default, you can specify the read preference :. You can specify the read preference in the --uri connection string. If specifying the read preference tags, include the readPreferenceTags option:. You can specify the read preference in using the --readPreference command-line option.

The command-line option takes a string if specifying only the read preference mode:. Specify the hostname of the mongos instance in the --uri connection string.

Starting in version 4. To restore data to a MongoDB deployment that has access control enabled, the restore role provides the necessary privileges to restore data from backups if the data does not include system. If the backup data includes system. As such, the user requires additional privileges to perform createCollection and convertToCapped actions on the system.

Both the built-in roles dbAdmin and dbAdminAnyDatabase provide the additional privileges. To run with --oplogReplaycreate a user-defined role that has anyAction on anyResource. Grant only to users who must run mongorestore with --oplogReplay. Increases the amount of internal reporting returned on standard output or in log files.

Increase the verbosity with the -v form by including the option multiple times, e. Runs mongorestore in a quiet mode that attempts to limit the amount of output. The following command-line options cannot be used in conjunction with --uri option:. Instead, specify these options as part of your --uri connection string.

Specifies a resolvable hostname for the mongod to which to connect. By default, the mongorestore attempts to connect to a MongoDB instance running on the localhost on port number Apart from taking a cold backup, it can also take hot backup. This tutorial provides several mongodump and mongorestore command examples that you can use to backup and restore a MongoDB using both. This is equivalent to the cold backup you would typically take in other database systems.

You should shutdown the mongodb instance before taking backup using this method. In this example, you are not really connecting to the mongod instance to take this backup. Go to the backup directory or any directory where you want to store the mongodb backupand execute the following mongodump command.

The —dbpath indicates the location of the mongodb database files. The above mongodump directory will create a dump sub-directory under the current directory. As you see below, it has taken a backup of both mongodevdb and mongoproddb database. The following example will connect to a running mongod instance, and take backup of a specific database. Next, go to the backup directory, and execute the mongodump command, and pass the database name, username and password parameters as shown below.

The dump directory will have a sub-directory for the database that was just backed-up. If the mongo instance has multiple database for example, mongodev and mongoprodexecute the mongodump command couple of time as shown below to backup both the database.

Instead of backing up all the collections in a particular database, you can also backup specific collections. The following example connects to mongodevdb database and does a backup of only employee collection.

In all the above examples, mongodump created a dump directory under the current directory from where the command was executed. Instead, if you want to backup mongoDB to a specific location, specify the —out parameter as shown below. In all the previous example we executed the mongodump command from the same server where the mongo database instance was running. However, you can also connect to a mongodb instance running on a different server, and take a backup of that.

In case of an disaster where you lost your mongoDB database, you can use this command to restore the database. Or, you can just use this command to restore the database on a different server for testing purpose. Next, go to the directory where the backup is located, and execute the restore command as shown below. The following example will restore only the mongodevdb. In the above two examples, mongorestore will perform a merge if it sees that the database already exists.Use this tutorial to install MongoDB 4.

How To Dump Mongodb By Using Mongodump Tool with Examples

Events Worldwide community events. Customers Who uses MongoDB. Consulting Accelerate success with MongoDB. Partners Find or become a partner.This tutorial describes the process for creating backups and restoring data using the utilities provided with MongoDB. The mongodump and mongorestore utilities work with BSON data dumps, and are useful for creating backups of small deployments. For resilient and non-disruptive backups, use a file system or block-level disk snapshot function, such as the methods described in the MongoDB Backup Methods document.

For 4. Because mongodump and mongorestore operate by interacting with a running mongod instance, they can impact the performance of your running database. Not only do the tools create traffic for a running database instance, they also force the database to read all data through memory.

The mongorestore and mongodump utilities work with BSON data dumps, and are useful for creating backups of small deployments. Use these tools for backups if other backup methods, such as MongoDB Cloud Manager or file system snapshots are unavailable. To run mongodump against a MongoDB deployment that has access control enabled, you must have privileges that grant find action for each database to back up.

The built-in backup role provides the required privileges to perform backup of any and all databases. Changed in version 3. Previously, users required read access on this collection. The mongodump utility backs up data by connecting to a running mongod.

The utility can create a backup for an entire server, database or collection, or can use a query to backup just part of a collection.

When you run mongodump without any arguments, the command connects to the MongoDB instance on the local system e. To backup data from a mongod instance running on the same machine and on the default port ofuse the following command:. You can also specify the --host and --port of the MongoDB instance that the mongodump should connect to. For example:. To specify a different output directory, you can use the --out or -o option:.

To limit the amount of data included in the database dump, you can specify --db and --collection as options to mongodump. Use the --oplog option with mongodump to collect the oplog entries to build a point-in-time snapshot of a database within a replica set. With --oplogmongodump copies all the data from the source database as well as all of the oplog entries from the beginning to the end of the backup procedure. This operation, in conjunction with mongorestore --oplogReplayallows you to restore a backup that reflects the specific moment in time that corresponds to when mongodump completed creating the dump file.

The --host and --port options for mongodump allow you to connect to and backup from a remote host. Consider the following example:. On any mongodump command you may, as above, specify username and password credentials to specify database authentication. To restore data to a MongoDB deployment that has access control enabled, the restore role provides the necessary privileges to restore data from backups if the data does not include system.

If the backup data includes system. As such, the user requires additional privileges to perform createCollection and convertToCapped actions on the system. Both the built-in roles dbAdmin and dbAdminAnyDatabase provide the additional privileges. To run with --oplogReplaycreate a user-defined role that has anyAction on anyResource.
