 - The frontend is a Next.js standalone Node runtime behind Traefik on internal port `3000`.
 - Alertmanager has been removed from this stack. Prometheus scraping and Grafana provisioning remain intact.
 - Dockerfiles live only in this deployment repository, and compose is intentionally wired only for the nested production layout.
+
+## Backups and restores
+The deployment repo owns backup automation in `scripts/`. Backups include:
+- PostgreSQL dump from the `db` service.
+- Django media files from the `django_media` Docker volume.
+- Deployment, backend, and frontend `.env` files when present.
+
+The scripts expect this production layout:
+```text
+guilan-ace-deployment/
+  .env
+  backend/guilan-ace-backend/.env
+  frontend/guilan-ace-frontend/.env
+  docker-compose.yml
+```
+
+Add these backup variables to `guilan-ace-deployment/.env`:
+```env
+S3_BACKUP_BUCKET=c284984
+S3_BACKUP_PREFIX=backup/guilan-ace
+S3_BACKUP_REGION=us-east-1
+S3_BACKUP_ENDPOINT_URL=https://c284984.parspack.net
+S3_BACKUP_ACCESS_KEY_ID=replace-with-access-key
+S3_BACKUP_SECRET_ACCESS_KEY=replace-with-secret-key
+BACKUP_ENCRYPTION_PASSPHRASE=replace-with-long-random-passphrase
+BACKUP_LOCAL_KEEP_LATEST=3
+BACKUP_REMOTE_KEEP_LATEST=10
+```
+
+Install script dependencies on the server:
+```bash
+sudo apt-get update
+sudo apt-get install -y docker-compose-plugin rclone openssl
+chmod +x ~/guilan-ace-deployment/scripts/*.sh
+```
+
+Create a manual local backup:
+```bash
+cd ~/guilan-ace-deployment
+./scripts/backup.sh
+```
+
+Create, encrypt, upload, and rotate an S3 backup:
+```bash
+cd ~/guilan-ace-deployment
+./scripts/backup-upload-s3.sh
+```
+
+Restore from a local backup archive:
+```bash
+cd ~/guilan-ace-deployment
+./scripts/restore.sh backups/guilan-ace-backup-YYYYMMDD-HHMMSS.tar.gz
+docker compose up -d --build
+```
+
+Restore the latest encrypted S3 backup:
+```bash
+cd ~/guilan-ace-deployment
+./scripts/restore-from-s3.sh latest
+docker compose up -d --build
+```
+
+Restore only selected parts by setting skip flags:
+```bash
+RESTORE_SKIP_ENV=1 ./scripts/restore.sh backups/guilan-ace-backup-YYYYMMDD-HHMMSS.tar.gz
+RESTORE_SKIP_DB=1 RESTORE_SKIP_MEDIA=1 ./scripts/restore-from-s3.sh latest
+```
+
+Database restore recreates the configured database and is destructive unless `RESTORE_SKIP_DB=1` is set.
+
+Run encrypted S3 backups periodically with cron:
+```bash
+crontab -e
+```
+
+Example: run every day at `03:30` server time and write logs to `backups/backup.log`:
+```cron
+30 3 * * * cd /home/ubuntu/guilan-ace-deployment && ./scripts/backup-upload-s3.sh >> /home/ubuntu/guilan-ace-deployment/backups/backup.log 2>&1
+```
+
+Example: run every 6 hours:
+```cron
+0 */6 * * * cd /home/ubuntu/guilan-ace-deployment && ./scripts/backup-upload-s3.sh >> /home/ubuntu/guilan-ace-deployment/backups/backup.log 2>&1
+```
