# Use with Docker Swarm
|
||
|
|
|
||
|
|
By default, Docker Swarm will restart stopped containers automatically, even when manually stopped.
|
||
|
|
If you plan to have your containers / services stopped during backup, this means you need to apply the `on-failure` restart policy to your service's definitions.
|
||
|
|
A restart policy of `always` is not compatible with this tool.

When running in Swarm mode, it's also advised to set a hard memory limit on your service (~25MB should be enough in most cases, but if you backup large files above half a gigabyte or similar, you might have to raise this in case the backup exits with `Killed`):
|
||
|
|
|
||
|
|
```yml
|
||
|
|
services:
|
||
|
|
backup:
|
||
|
|
image: offen/docker-volume-backup:v2
