gordonchan/postgres-s3-backup repository overview

⁠gordonchan/postgres-s3-backup

A Docker image designed to make daily backups of a Postgres database at 3pm UTC (3am NZST). Backups are stored locally on the container but are also uploaded to Amazon S3⁠. Email notifications are delivered on every backup attempt.

backup⁠ is used to manage backups and whenever⁠ is used to create the cron job. The main backup configuration file can be found here⁠.

This Docker image was created for my own selfish needs. It could be useful for others or be used as an example to create your own version.
