mongo-git-backup Build Status npm version

The tool exports text dump (via mongoexport) of given MongoDB database to given Git repository and restores it back (via mongoimport). Please read MIT License agreement before use.

Pros

  • Github and Bitbucket are safe places to store data and history of data changes.
  • You don't need to pay for a storage if you're able to create private repos (on Bitbucket they're free).
  • You can make as many backups as you can and as often as you want since Git stores diffs instead of storing everything.
  • Git GUI clients (including web UI) allow to nicely show diffs between two versions (two commits) of data.

Cons

  • Likely, it isn't good for big databases.

Install

npm install -g mongo-git-backup

To run the tool on boot you need to install pm2.

npm install -g pm2

  • --db - DB name you want to restore (required)
  • --repo - a Git repository where backup is stored (required)
  • --branch - a branch of the Git repository (optional, master by default)
  • --checkout - switches to a specified commit or git tag (optional)

Example:

mongo-git-backup import --db=test --repo=git@github.com:finom/mongo-git-backup.git --branch=test --checkout=tags/foo

Tip: add this command to NPM scripts to run it easier.

API

There are two functions exported: exportToGit and importFromGit. Both functions return promise. The list of arguments is the same as for CLI.

const { exportToGit, importFromGit } = require('mongo-git-backup');
 
const options = {
    db: 'test',
    repo: 'git@github.com:finom/mongo-git-backup.git',
    branch: 'test'
}
 
exportToGit(options).then(() => importFromGit(options));
