This is a simple AWS Lambda function that uses mongodump to backup a MongoDB database to S3. It uses Serverless to zip up the directory and deploy to AWS.

Deployment instructions

Create a .env file in the root directory and add the following environment variables:

export MONGO_URL = mongodb://<user>:<password>@<host>:<port>/<database>
export S3_PATH = <s3bucket>/<folder>/...etc

Source the environment file so Serverless can access the values:

. ./.env

Deploy the lambda function with Serverless:

serverless deploy --aws-profile profilename

Your function is now deployed and will run every 2 hours. Change the execution frequency in serverless.yml.

Lambda configuration

The serverless.yml file contains a set of default configuration for the lambda. You can change these settings to fit your needs.
