S3 backup cleaner script

Script for removing old backups from s3 (old in this case means > 1 month old). Keeps first backup for each day.

Running

Production

I deployed it using Serverless framework to AWS Lambda where it's running once a day (see serverless.example.yml file) - but you can do it whatever way you'd like.

Following env vars need to be specified:

• S3_BUCKET_NAME (e.g. some-bucket)
• FILE_PATH_PREFIX: prefix for which the files are listed (e.g. backups/db_ if files are in backups dir and named db_<date>)

Also, the function must have access to the bucket setup along with proper permissions.

Locally

1. Clone this repo.
2. Run npm install
3. Configure AWS credentials.
4. Set env vars.
5. Run the script using node run.js.
