Create a backup of DTR
|
|
|
|
## Usage
|
|
|
|
```bash
|
|
docker run -i --rm docker/dtr \
|
|
backup [command options] > backup.tar
|
|
```
|
|
|
|
## Description
|
|
|
|
|
|
This command creates a tar file with the contents of the volumes used by
|
|
DTR, and prints it. You can then use the `restore` command to restore the data
|
|
from an existing backup.
|
|
|
|
Note:
|
|
|
|
* This command only creates backups of configurations, and image metadata.
|
|
It doesn't back up users and organizations. Users and organizations can be
|
|
backed up when performing a UCP backup.
|
|
|
|
It also doesn't back up the Docker images stored in your registry.
|
|
You should implement a separate backup policy for the Docker images stored
|
|
in your registry, taking in consideration whether your DTR installation is
|
|
configured to store images on the filesystem or using a cloud provider.
|
|
|
|
* This backup contains sensitive information and should be
|
|
stored securely.
