backup

1---
2# Back up everything on this host: /docker services, data paths, appliances.
3# Every item records its outcome in `backup_results` instead of failing the
4# host, so one broken service never stops the others from being backed up.
5# The maintenance stage (backup.yml) evaluates the results and fails the run.
