Add backup/restore functionality for the SQLite database. Users can trigger manual backups, configure automatic backups on an interval with retention policies, list/download/delete backups, and restore from any backup. - Backup engine using VACUUM INTO (safe with WAL mode) - Backup metadata tracked in DB, files stored in DATA_DIR/backups/ - Settings: backup_enabled, backup_interval_hours, backup_retention_count - API: POST/GET/DELETE /api/backups, download, restore endpoints - Autobackup via cron scheduler with configurable interval - Retention: prune on startup, after each backup (manual and auto) - Orphan cleanup: removes backup files without metadata on startup - Restore: replaces DB and triggers graceful server shutdown - Settings UI: /settings/backup with toggle, interval, retention config - Backup list with download, delete, restore actions - i18n: English and Russian translations

# Phase 4: Retention & Cleanup
|
|
|
|
**Status:** ⬜ Not Started
|
|
**Parent plan:** [PLAN.md](./PLAN.md)
|
|
**Domain:** backend
|
|
|
|
## Objective
|
|
Implement automatic retention enforcement — prune old backups after each backup
|
|
operation and on server startup.
|
|
|
|
## Tasks
|
|
|
|
- [ ] Task 1: Add `Prune()` method to backup engine
|
|
- Delete backups exceeding retention count (keep N most recent)
|
|
- Return count of pruned backups
|
|
- [ ] Task 2: Call Prune after every CreateBackup (both manual and auto)
|
|
- [ ] Task 3: Call Prune on server startup
|
|
- [ ] Task 4: Clean up orphaned files (files in backup dir not in metadata)
|
|
- [ ] Task 5: Log pruning results
|
|
|
|
## Files to Modify/Create
|
|
- `internal/backup/engine.go` — add Prune method
|
|
- `cmd/server/main.go` — call prune on startup
|
|
|
|
## Acceptance Criteria
|
|
- Backups exceeding retention count are automatically deleted
|
|
- Both file and metadata are removed during pruning
|
|
- Orphaned files (no metadata) are cleaned up
|
|
- Pruning runs after each backup and on startup
|
|
- Pruning results logged
|
|
