Quick and dirty database dump to S3 via Node.js

We are implementing database dumping which is straightforward but can be tedious to setup. Here's our setup:

  1. Create AWS user for db backups (e.g. db-backups-{{app}})
    • Save credentials in a secure location
    • If adding db scrubbing, use a separate user (e.g db-scrubs-{{app}})
  2. Create bucket for S3 access logging (e.g. s3-access-log-{{app}})
  3. Create consistently named bucket for db dumps (e.g. db-backups-{{app}})
    • Enable logging to s3-access-log-{{app}} with prefix of db-backups-{{app}}
  4. Add IAM policy for bucket access
  • Select user -> Choose "Add inline policy"
