rehtlaw / mongo-backup-cli

a python-based CLI that creates and restores backups of your mongodb server

A command-line tool to back up your MongoDB databases

Usage

• Installation

pip install -U git+https://github.com/rehtlaw/mongo-backup-cli.git

• Backing up all collections of a database

mongo-backup backup --uri mongodb://username:[e-mail] --db-name name_of_db

this will put a zip in the current directory named backup-{year}_{month}_{day}-{db_name}.zip which contains one json file per collection

• Backing up multiple specific collections

mongo-backup backup --uri mongodb://username:[e-mail] --db-name
name_of_db --collections col1,col2,col3

This will also put a zip in your current directory the same as the other command does, but this will only have the json files of the collections your provided. This also works when you pass it only 1 collection, but it will still end up with a .zip file

• Restoring a backup

mongo-backup restore backup.zip --uri mongodb://username:[e-mail]
--db-name name_of_db 

This will upload all the .json files inside the .zip file to the MongoDB server that is provided and delete all the data of the backed up collections that was previously on the server.

WARNING: This also deletes any collections with the same names as the ones in the backup, but it will leave any other collection untouched. Meaning you cannot merge 2 collections with this tool.

• Setting up a replica set

mongo-backup replica --set-name myRepSet --primary node1-db.com:27017 --secondary node2-db.com:27017,node3-db.com:27018

This will set up a replica set, using the server provided with --primary as the primary node and all the servers provided with --secondary as secondary nodes. Note: You still need to configure the servers themselves with the replSet name, either as a start parameter or in the configuration files. (see here)
