Node MongoDB / S3 Backup

This is a package that makes backing up your mongo databases to S3 simple. The binary file is a node cronjob that runs at midnight every day and backs up the database specified in the config file.

Installation

npm install mongodb_s3_backup -g

Configuration

To configure the backup, you need to pass the binary a JSON configuration file. There is a sample configuration file supplied in the package (config.sample.json). The file should have the following format:

{
  "mongodb": {
    "host": "localhost",
    "port": 27017,
    "username": false,
    "password": false,
    "db": "database_to_backup"
  },
  "s3": {
    "key": "your_s3_key",
    "secret": "your_s3_secret",
    "bucket": "s3_bucket_to_upload_to",
    "destination": "/"
  },
  "cron": {
    "time": "11:59",
  }
}

Crontabs

You may optionally substitute the cron "time" field with an explicit "crontab" of the standard format 0 0 * * *.

  "cron": {
    "crontab": "0 0 * * *"
  }

Note: The version of cron that we run supports a sixth digit (which is in seconds) if you need it.

Timezones

The optional "timezone" allows you to specify timezone-relative time regardless of local timezone on the host machine.

  "cron": {
    "time": "00:00",
    "timezone": "America/New_York"
  }

You must first npm install time to use "timezone" specification.

Running

To start a long-running process with scheduled cron job:

mongodb_s3_backup <path to config file>

To execute a backup immediately and exit:

mongodb_s3_backup -n <path to config file>
