# Stop containers during backup
|
|
|
|
{: .note }
|
|
In case you are running Docker in Swarm mode, [dedicated documentation](./use-with-docker-swarm.html) on service and container restart applies.
|
|
|
|
In many cases, it will be desirable to stop the services that are consuming the volume you want to backup in order to ensure data integrity.
|
|
This image can automatically stop and restart containers and services.
|
|
By default, any container that is labeled `docker-volume-backup.stop-during-backup=true` will be stopped before the backup is being taken and restarted once it has finished.
|
|
|
|
In case you need more fine grained control about which containers should be stopped (e.g. when backing up multiple volumes on different schedules), you can set the `BACKUP_STOP_DURING_BACKUP_LABEL` environment variable and then use the same value for labeling:
|
|
|
|
```yml
|
|
version: '3'
|
|
|
|
services:
|
|
app:
|
|
# definition for app ...
|
|
labels:
|
|
- docker-volume-backup.stop-during-backup=service1
|
|
|
|
backup:
|
|
image: offen/docker-volume-backup:v2
|
|
environment:
|
|
BACKUP_STOP_DURING_BACKUP_LABEL: service1
|
|
volumes:
|
|
- data:/backup/my-app-backup:ro
|
|
- /var/run/docker.sock:/var/run/docker.sock:ro
|
|
|
|
volumes:
|
|
data:
|
|
```
