# Purpose {{{
|
|||
|
|
## Backup data of a Docker container.
|
|||
|
|
## To do that, the script will :
|
|||
|
|
## Stop the corresponding container (or docker if no related service is found)
|
|||
|
|
## Make a archive of the container's data to a backup path
|
|||
|
|
## Clean old backup
|
|||
|
|
## Restart the container service (or docker.service)
|
|||
|
|
# }}}
|
|||
|
|
# How-to use {{{
|
|||
|
|
## The container and it's data directory should have the same name.
