|
|
Automatically detects and backs up volumes, mysql, mariadb and postgres databases in a docker-compose setup.
|
|
|
|
* Each service in the compose setup is configured with a label
|
|
to enable backup of volumes or databases
|
|
* When backup starts a new instance of the container is created
|
|
mapping in all the needed volumes. It will copy networks etc
|
|
to ensure databases can be reached
|
|
* Volumes are mounted to `/volumes/<service_name>/<path>`
|
|
in the backup process container. `/volumes` is pushed into restic
|
|
* Databases are backed up from stdin / dumps into restic using path `/databases/<service_name>/dump.sql`
|
|
* Cron triggers backup at 2AM every day
|

|
|
|
|

|
|
labels:
|
|
restic-compose-backup.volumes: true
|
|
# These volumes will be backed up
|
|
volumes:
|
|
# Docker volume

|
image: some_image
|
|
labels:
|
|
restic-compose-backup.volumes: true
|
|
restic-compose-backup.volumes.include: "files,data"
|
|
volumes:
|
|
# Source don't match include filter. No backup.
|
|
- media:/srv/media
|
|
# Matches include filter
|
|
- files:/srv/files
|
