# docker/dtr restore
|
|
|
|
Create a new DTR cluster from an existing backup
|
|
|
|
## Usage
|
|
|
|
```bash
|
|
$ docker run -i --rm docker/dtr \
|
|
restore [command options] < backup.tar
|
|
```
|
|
|
|
## Description
|
|
|
|
This command performs a fresh installation of DTR, and reconfigures it
|
|
with configuration data from a tar file generated by the 'backup' command.
|
|
The command starts by installing DTR, restores the configurations
|
|
stored on etcd, and then restores the repository metadata stored
|
|
on RethinkDB.
|
|
|
|
This command does not restore Docker images. You should implement a separate
|
|
restore procedure 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.
|
|
|
|
After restoring DTR, you can add more nodes to the DTR cluster with
|
|
the 'join' command.
