# Session 0008: Schedule Management & Backup Coverage System

**Date:** 2026-02-23
**Status:** Completed
**Origin:** MDF Webseiten session 0040

## Work Done

- [x] Fixed `backup-all.sh` — was appending env suffix twice → files landed in `.../dev/dev/`
- [x] Moved stranded double-nested backup files to correct directories
- [x] Version-controlled `offsite.py` and `backup-all.sh` into infrastructure repo
- [x] Added `_backup_generic()` function to ops CLI — tar-based fallback for projects without a dedicated CLI
- [x] Added `backup:` config blocks to `registry.yaml` for MDF (03:15), SeriousLetter (03:00), Coolify (04:00)
- [x] Created `gen-timers.py` — reads registry, generates systemd `.service` + `.timer` units automatically
- [x] Added `ops gen-timers [--dry-run]` command — replaces legacy backup-all, mdf-backup, seriousletter-backup timers
- [x] Created `schedule.py` FastAPI router:
  - `GET /api/schedule/` — returns backup config for all projects
  - `PUT /api/schedule/{project}` — updates config, writes registry via nsenter, regenerates timers
- [x] Added "Schedules" nav item to dashboard sidebar (clock icon)
- [x] Schedule page: table showing all projects with enabled/schedule/envs/offsite/retention columns
- [x] Schedule edit modal: toggle, time picker, env checkboxes, offsite section, retention fields

## Key Decisions / Learnings

- registry.yaml drives both systemd timers and the dashboard schedule UI — single source of truth
- `gen-timers` must auto-remove orphan timers (e.g. `backup-coolify.timer`) — prevents ghost schedules
- `PUT /api/schedule/{project}` writes via nsenter (not inside container) because systemd lives on host
- `backup-all.sh` must NOT append `/$env` suffix if the CLI already appends it internally
