# Backupbot II: This Time It's Easily Configurable

Automatically backup files from running Docker Swarm services based on labels.

## Background

There are lots of Docker volume backup systems; all of them have one or both of
these problems:
 - You need to define all the volumes to back up in the configuration system
 - Backups require services to be stopped to take consistent copies

Backupbot II tries to solve these problems by **letting you define how to back up your services using Docker labels**, so you can **easily collect your backups for use with another system** like docker-volume-backup.

## TODO

A first stab:
- [x] Make a Docker image of this
- [x] Add secret handling for database backups
- [ ] SSH remote storage
  - [ ] Add SSH key handling
  - [ ] SSH host key checking
- [x] S3 remote storage
- [x] Re-add `crond` support

Future:
- [ ] Continuous linting with shellcheck
- [ ] Rip out or improve Restic stuff

## Label format

```
services:
  db:
    deploy:
      labels:
        backupbot.backup: "true"
        backupbot.backup.repos: "$some_thing"
        backupbot.backup.at: "* * * * *"
        backupbot.backup.pre-hook: 'mysqldump -u root -p"$(cat /run/secrets/db_root_password)" -f /tmp/dump/dump.db'
        backupbot.backup.post-hook: "rm -rf /tmp/dump/dump.db"
        backupbot.backup.path: "/tmp/dump/"
```
