docker/dtr backup

Create a backup of DTR

Usage

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.
