Owner

Goal

Implement Priority 2 from projects/host-facts-refactor-roadmap.md: separate host backup intent from backup mechanism/policy.

Acceptance Checklist

Introduce host facts for backup-relevant data classes.
Cover at least:
- home backups
- snapshot intent
- server/service data paths
Treat /srv/services on vega as a first-class backed-up service-state path.
Keep retention, schedule, repo target, and encryption policy in service modules rather than in host facts.

Proposed Shape

nixosConfig.backup = {
  home.enable = true;
  snapshots.home.enable = true;
  dataPaths = [ "/srv/stacks" "/srv/services" "/mnt/storage" ];
};

Potential Consumers

modules/services/backrest.nix
modules/services/btrbk-home.nix
future server backup modules
