## Tips
|
|
|
|
## Hostnames
|
|
Hostname is used for identifying what you are backing up. You may want to specify this on your container.
|
|
|
|
### Backing up from another container
|
|
Mount all volumes from your existing container with `--volumes-from` and then back up by providing the paths to those volumes. If there are more than one volumes, you'll want to use the above tip for mulitple backup sources
|
|
|
|
### Restoring a backup
|
|
On your running container, execute `/restore.sh`. That should be that! Eg. `docker exec my_backup_container /restore.sh`
|
|
|
|
### Backup to any rclone destination
|
|
This image also contains [rclone](https://rclone.org). This allows you to target any destination supported by rclone. Check out the [official documentation](https://restic.readthedocs.io/en/stable/030_preparing_a_new_repo.html#other-services-via-rclone) to see how to configure this.
|
|
|
|
### Pre/post backup/restore scripts
|
|
Before and after any backup or restore, scripts located in `/scripts/{backup,restore}/{before,after}/` will be executed. This can be used to do things like snapshotting a database before backing it up and restoring the contents.
