## Contents

### Compose Files
All Docker Compose files from Dokploy-managed projects:
\`\`\`
$(ls -1 $BACKUP_DIR/compose/)
\`\`\`

### Stack Files
Standalone stack definitions:
\`\`\`
$(ls -1 $BACKUP_DIR/stacks/ 2>/dev/null || echo "None")
\`\`\`

### Traefik Configuration
Reverse proxy configuration backed up to ./traefik/

## Restoration
To restore these configurations:
1. Copy compose files to /etc/dokploy/compose/<project>/code/
2. Copy stack files to ~/ on the controller
3. Copy Traefik config to /etc/dokploy/traefik/
4. Redeploy via Dokploy UI or docker stack deploy

## Services Backed Up
$(ssh -o ConnectTimeout=10 -i ~/.ssh/id_ed25519 $CONTROLLER "docker service ls --format '- {{.Name}}'" 2>/dev/null || echo "Unable to fetch service list")
