mongodb_s3_backup

A tool to help backup your mongodb databases to s3.

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.

npm install mongodb_s3_backup -g

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": "/",
    "encrypt": true,
    "region": "s3_region_to_use"
  },
  "cron": {
    "time": "11:59",
  }
}

All options in the "s3" object, except for desination, will be directly passed to knox, therefore, you can include any of the options listed in the knox documentation.

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.

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.

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>
