docker/dtr backup预计阅读时间: 1 分钟
Create a backup of DTR
docker run -i --rm docker/dtr \ backup [command options] > backup.tar
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.
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.
