This is a fork and restructuring of schickling's [postgres-backup-s3](https://github.com/schickling/dockerfiles/tree/master/postgres-backup-s3) and [postgres-restore-s3](https://github.com/schickling/dockerfiles/tree/master/postgres-restore-s3). # Overview
This project provides Docker containers to backup/restore a PostgreSQL database to/from AWS S3 (or a compatible service like DigitalOcean Spaces). Both one-off and periodic/scheduled backups are supported.
See [`backup/README.md`](/backup/README.md) and [`restore/README.md`](/restore/README.md) for further instructions. # Credit where due

### Notes
#### Periodic backups
The `SCHEDULE` variable is determines backup frequency. It is optional -- without it, the backup will run once at start up. More information about the scheduling can be found [here](http://godoc.org/github.com/robfig/cron#hdr-Predefined_schedules).
### Automatic Periodic Backups #### Docker
Docker Compose is by no means required, you can use plain ol' Docker too -- just set the required env vars with the `-e` flag.
You can additionally set the `SCHEDULE` environment variable like `-e SCHEDULE="@daily"` to run the backup automatically.
More information about the scheduling can be found [here](http://godoc.org/github.com/robfig/cron#hdr-Predefined_schedules).
