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

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
