[ ] **Step 4: Commit** ```bash git add backend/backup/adapters/ssh.py backend/backup/adapters/database.py backend/backup/adapters/__init__.py git commit -m "feat: add SSH and database source adapters - SSHAdapter using Paramiko for remote file access - DatabaseAdapter using native CLI tools (pg_dump, mysqldump) - Updated adapter factory with all source types" ``` --- ### Task 17: Scheduler Integration **Files:** - Create: `backend/backup/scheduler.py` - Modify: `backend/app/main.py` - [ ] **Step 1: Create scheduler service** `backend/backup/scheduler.py`: ```python from apscheduler.schedulers.asyncio import AsyncIOScheduler from apscheduler.triggers.cron import CronTrigger from sqlalchemy.ext.asyncio import AsyncSession from app.database import AsyncSessionLocal from app.models import Schedule, Job from backup.engine import BackupEngine class BackupScheduler: def __init__(self): self.scheduler = AsyncIOScheduler() def start(self): self.scheduler.start() def shutdown(self): self.scheduler.shutdown() def add_job(self, schedule_id: int, cron_expression: str): """Add a scheduled job.""" trigger = CronTrigger.from_crontab(cron_expression) self.scheduler.add_job( func=self._execute_scheduled_job, trigger=trigger, id=f"schedule_{schedule_id}", args=[schedule_id], replace_existing=True, misfire_grace_time=900 # 15 minutes ) def remove_job(self, schedule_id: int): """Remove a scheduled job.""" job_id = f"schedule_{schedule_id}" try: self.scheduler.remove_job(job_id) except Exception: pass async def _execute_scheduled_job(self, schedule_id: int): """Execute a scheduled backup job.""" async with AsyncSessionLocal() as db: from sqlalchemy import select result = await db.execute( select(Schedule).where(Schedule.id == schedule_id) ) schedule = result.scalar_one_or_none() if not schedule or not schedule.enabled: return engine = BackupEngine(db) await engine.execute_job(schedule.job_id, triggered_by="schedule") # Global scheduler instance scheduler = BackupScheduler() ``` - [ ] **Step 2: Integrate scheduler with FastAPI** Modify `backend/app/main.py`: ```python from fastapi import FastAPI from fastapi.middleware.cors import CORSMiddleware from app.routers import sources, jobs, executions, backups, settings, dashboard from app.database import engine, Base from backup.scheduler import scheduler app = FastAPI(title="Backup Tool API", version="0.1.0") # CORS app.add_middleware( CORSMiddleware, allow_origins=["http://localhost:3000"], allow_credentials=True, allow_methods=["*"], allow_headers=["*"], ) # Include routers app.include_router(sources.router) app.include_router(jobs.router) app.include_router(executions.router) app.include_router(backups.router) app.include_router(settings.router) app.include_router(dashboard.router) @app.on_event("startup") async def startup(): async with engine.begin() as conn: await conn.run_sync(Base.metadata.create_all) # Start scheduler scheduler.start() # Load existing schedules from sqlalchemy import select from app.models import Schedule async with AsyncSessionLocal() as db: result = await db.execute(select(Schedule).where(Schedule.enabled == True)) schedules = result.scalars().all() for schedule in schedules: scheduler.add_job(schedule.id, schedule.cron_expression) @app.on_event("shutdown") async def shutdown(): scheduler.shutdown() @app.get("/api/health") async def health_check(): return {"status": "healthy"} ``` - [ ] **Step 3: Commit** ```bash git add backend/backup/scheduler.py backend/app/main.py git commit -m "feat: add APScheduler integration for cron-based job scheduling - BackupScheduler class wrapping APScheduler - Auto-load enabled schedules on startup - Graceful shutdown on app stop" ``` --- ### Task 18: Retention Policy **Files:** - Create: `backend/backup/retention.py` - [ ] **Step 1: Create retention policy logic** `backend/backup/retention.py`: ```python import os import shutil from datetime import datetime, timedelta from typing import List from sqlalchemy.ext.asyncio import AsyncSession from sqlalchemy import select from app.models import Job, Backup, JobExecution class RetentionPolicy: def __init__(self, db: AsyncSession): self.db = db async def apply_policy( self, job_id: int, policy_type: str = "count", keep_count: int = 10, keep_days: int = 30 ): """Apply retention policy to a job's backups.""" if policy_type == "count": await self._apply_count_policy(job_id, keep_count) elif policy_type == "days": await self._apply_days_policy(job_id, keep_days) elif policy_type == "all": pass # Keep all backups async def _apply_count_policy(self, job_id: int, keep_count: int): """Keep only the last N backups.""" result = await self.db.execute( select(Backup) .join(JobExecution) .where(JobExecution.job_id == job_id) .order_by(Backup.created_at.desc()) .offset(keep_count) ) old_backups = result.scalars().all() for backup in old_backups: await self._delete_backup(backup) async def _apply_days_policy(self, job_id: int, keep_days: int): """Delete backups older than N days.""" cutoff = datetime.utcnow() - timedelta(days=keep_days) result = await self.db.execute( select(Backup) .join(JobExecution) .where( JobExecution.job_id == job_id, Backup.created_at < cutoff ) ) old_backups = result.scalars().all() for backup in old_backups: await self._delete_backup(backup) async def _delete_backup(self, backup: Backup): """Delete backup files and database record.""" # Delete files if os.path.exists(backup.storage_path): if os.path.isdir(backup.storage_path): shutil.rmtree(backup.storage_path) else: os.unlink(backup.storage_path) # Delete database record await self.db.delete(backup) ``` - [ ] **Step 2: Integrate retention in engine** Modify `backend/backup/engine.py` to add retention application after successful backup: Add at the end of the `execute_job` method, after storing backup metadata: ```python # Apply retention policy from backup.retention import RetentionPolicy retention = RetentionPolicy(self.db) await retention.apply_policy( job_id=job_id, policy_type="count", # TODO: Read from settings keep_count=10 ) ``` - [ ] **Step 3: Commit** ```bash git add backend/backup/retention.py git commit -m "feat: add retention policy management - Count-based retention (keep last N backups) - Days-based retention (delete older than N days) - Automatic cleanup after successful backup" ``` --- ### Task 19: Frontend Build Integration **Files:** - Modify: `backend/app/main.py` - Modify: `backend/requirements.txt` - [ ] **Step 1: Add static file serving** Modify `backend/app/main.py` to include static file serving: ```python from fastapi import FastAPI from fastapi.middleware.cors import CORSMiddleware from fastapi.staticfiles import StaticFiles from fastapi.responses import FileResponse import os from app.routers import sources, jobs, executions, backups, settings, dashboard from app.database import engine, Base from backup.scheduler import scheduler app = FastAPI(title="Backup Tool API", version="0.1.0") # CORS (only in development) app.add_middleware( CORSMiddleware, allow_origins=["http://localhost:3000"], allow_credentials=True, allow_methods=["*"], allow_headers=["*"], ) # Include routers app.include_router(sources.router) app.include_router(jobs.router) app.include_router(executions.router) app.include_router(backups.router) app.include_router(settings.router) app.include_router(dashboard.router) # Serve static files in production static_dir = os.path.join(os.path.dirname(__file__), "../static") if os.path.exists(static_dir): app.mount("/", StaticFiles(directory=static_dir, html=True), name="static") @app.on_event("startup") async def startup(): async with engine.begin() as conn: await conn.run_sync(Base.metadata.create_all) # Start scheduler scheduler.start() # Load existing schedules from sqlalchemy import select from app.models import Schedule from app.database import AsyncSessionLocal async with AsyncSessionLocal() as db: result = await db.execute(select(Schedule).where(Schedule.enabled == True)) schedules = result.scalars().all() for schedule in schedules: scheduler.add_job(schedule.id, schedule.cron_expression) @app.on_event("shutdown") async def shutdown(): scheduler.shutdown() @app.get("/api/health") async def health_check(): return {"status": "healthy"} # Fallback for SPA routing @app.get("/{path:path}") async def catch_all(path: str): index_file = os.path.join(static_dir, "index.html") if os.path.exists(index_file): return FileResponse(index_file) return {"detail": "Not found"} ``` - [ ] **Step 2: Update requirements** Add to `backend/requirements.txt`: ``` aiofiles==23.2.1 ``` - [ ] **Step 3: Commit** ```bash git add backend/app/main.py backend/requirements.txt git commit -m "feat: add static file serving for production build - Serve built frontend from /static directory - SPA catch-all routing - Added aiofiles for async file operations" ``` --- ### Task 20: Documentation and Final Setup **Files:** - Create: `README.md` - Create: `.gitignore` -

All steps contain complete code. ### Type Consistency - Database models and Pydantic schemas are consistent - API endpoints return correct schema types - Adapter interface methods match across implementations --- ## Execution Handoff **Plan complete and saved to `docs/superpowers/plans/2026-05-11-backup-tool-implementation.md`.** **Two execution options:** **1. Subagent-Driven (recommended)** - I dispatch a fresh subagent per task, review between tasks, fast iteration **2. Inline Execution** - Execute tasks in this session using executing-plans, batch execution with checkpoints for review **Which approach?**
