3.3.5. MongoDB backups

A MongoDB backup is a database dump. Backups are created in Binary format.

Requirements:

  • To make backups of your databases, you have to ensure that you have installed mongodump utility that is compatible with the version of your database server.
  • There should be enough space in the directory where the temporary backup is created.
  • The database user must have the following privileges

Here is an example of configs for creating a backup of all collections in “example” database on MongoDB server. This job config defines rules to make database backups on MongoDB server running on localhost:

job_name: mongodb
type: mongodb
tmp_dir: /var/backup/dump_tmp
safety_backup: false
deferred_copying: false
sources:
  - name: mongodb
  	connect:
    	db_host: localhost
    	db_port: "27017"
    	db_user: mongo
    	db_password: mongoP@5s
  	target_dbs:
    	- example
  	target_collections:
    	- all
  	exclude_dbs: []
  	exclude_collections: []
  	gzip: true
storages_options:
  - storage_name: local
  	backup_path: /var/backup/dump
  	retention:
    	days: 7
    	weeks: 5
    	months: 5

If you need to configure additional storage or have questions about options, please visit the Job storage options page for more details.
