Configuring Backups for UCP and DTR
-
Back up UCP
- On the UCP server, get your UCP instance ID.
docker container run --rm \ --name ucp \ -v /var/run/docker.sock:/var/run/docker.sock \ docker/ucp:3.1.5 \ id - Create an encrypted backup. Enter your UCP instance ID from the previous command for the
--idflag.docker container run \ --log-driver none --rm \ --interactive \ --name ucp \ -v /var/run/docker.sock:/var/run/docker.sock \ docker/ucp:3.1.5 backup \ --passphrase "secretsecret" \ --id <Your UCP instance ID> > /home/cloud_user/ucp-backup.tar - List the contents of the backup file.
gpg --decrypt /home/cloud_user/ucp-backup.tar | tar --list
- On the UCP server, get your UCP instance ID.
-
Restore UCP from Backup
- First, uninstall UCP on the UCP manager server.
docker container run --rm -it \ -v /var/run/docker.sock:/var/run/docker.sock \ --name ucp \ docker/ucp:3.1.5 uninstall-ucp --interactive - Restore UCP from the backup.
docker container run --rm -i --name ucp \ -v /var/run/docker.sock:/var/run/docker.sock \ docker/ucp:3.1.5 restore --passphrase "secretsecret" < /home/cloud_user/ucp-backup.tar
- First, uninstall UCP on the UCP manager server.
-
Back up DTR
- On the DTR server, get the DTR replica ID.
docker volume ls - Look for a volume name that begins with
dtr-registry-. The string of letters and numbers at the end of this volume name us your DTR replica ID. - Back up the registry images.
sudo tar -zvcf dtr-backup-images.tar \ $(dirname $(docker volume inspect --format '{{.Mountpoint}}' dtr-registry-<replica-id>)) - Back up DTR metadata.
read -sp 'ucp password: ' UCP_PASSWORD; \ docker run --log-driver none -i --rm \ --env UCP_PASSWORD=$UCP_PASSWORD \ docker/dtr:2.6.6 backup \ --ucp-url https://<UCP Manager Private IP> \ --ucp-insecure-tls \ --ucp-username admin \ --existing-replica-id <replica-id> > dtr-backup-metadata.tar
- On the DTR server, get the DTR replica ID.
-
Restore DTR Backup
- Stop the existing DTR replica.
docker run -it --rm \ docker/dtr:2.6.6 destroy \ --ucp-insecure-tls \ --ucp-username admin \ --ucp-url https://<UCP Manager Private IP> - Restore images.
sudo tar -xzf dtr-backup-images.tar -C /var/lib/docker/volumes - Restore DTR metadata.
read -sp 'ucp password: ' UCP_PASSWORD; \ docker run -i --rm \ --env UCP_PASSWORD=$UCP_PASSWORD \ docker/dtr:2.6.6 restore \ --dtr-use-default-storage \ --ucp-url https://<UCP Manager Private IP> \ --ucp-insecure-tls \ --ucp-username admin \ --ucp-node <hostname> \ --replica-id <replica-id> \ --dtr-external-url <dtr-external-url> < dtr-backup-metadata.tar
- Stop the existing DTR replica.
