docker/ucp backupEstimated reading time: 1 minute
Create a backup of a UCP manager node
docker container run --log-driver none --rm -i \ --name ucp \ -v /var/run/docker.sock:/var/run/docker.sock \ docker/ucp \ backup [command options] > backup.tar
This command creates a tar file with the contents of the volumes used by
this UCP manager node, and prints it. You can then use the
restore command to
restore the data from an existing backup.
To create backups of a multi-node cluster, you only need to back up a single manager node. The restore operation will reconstitute a new UCP installation from the backup of any previous manager.
During the backup, UCP is temporarily stopped. This does not affect your applications.
The backup contains private keys and other sensitive information. Use the
--passphraseflag to encrypt the backup with PGP-compatible encryption.
