aibot88 Works with Docker volumes (caddy_data, pihole_data), configuration files, and .env secrets.
Infrastructure Backup and Restore Skill
Complete backup and disaster recovery procedures for network infrastructure including Docker volumes, configuration files, and secrets.
Quick Start
Quick full backup:
# Create backup directory
backup_dir="/home/dawiddutoit/projects/network/backups/full-$(date +%Y%m%d-%H%M%S)"
mkdir -p "$backup_dir"
# Backup Docker volumes
tar -czf "$backup_dir/pihole_data.tar.gz" \
-C /var/lib/docker/volumes/network_pihole_data/_data .
tar -czf "$backup_dir/caddy_data.tar.gz" \
-C /var/lib/docker/volumes/network_caddy_data/_data .
# Backup configuration
cp -r /home/dawiddutoit/projects/network/docker-compose.yml "$backup_dir/"
cp -r /home/dawiddutoit/projects/network/caddy "$backup_dir/"
cp -r /home/dawiddutoit/projects/network/config "$backup_dir/"
cp -r /home/dawiddutoit/projects/network/.env "$backup_dir/.env"
echo "Backup completed: $backup_dir"

When to Use This Skill
Explicit Triggers:
- "Backup infrastructure"
- "Restore from backup"
- "Disaster recovery"
- "Backup before upgrade"
- "Migrate to new server"
Implicit Triggers:
- Planning major infrastructure changes
- Before OS upgrade or Docker upgrade
- Hardware failure requiring migration
- Testing disaster recovery procedures
Debugging Triggers:
- "What should I backup?"
- "How to restore from backup?"
- "Disaster recovery plan?"
What This Skill Does
- Full Backup - Creates complete infrastructure backup (volumes + config)
- Volume Backup - Backs up Docker volumes (Pi-hole data, Caddy certificates)
- Config Backup - Backs up configuration files and .env secrets
- Full Restore - Restores complete infrastructure from backup
- Partial Restore - Restores specific components (volume or config only)
- Disaster Recovery - Complete rebuild procedure from backups
- Backup Management - Retention policies and cleanup procedures
Instructions
Use this skill to create and restore infrastructure backups. The skill provides workflows for:
- Full infrastructure backups (volumes + configuration + secrets)
- Partial backups (volumes only or configuration only)
- Full restoration from backups
- Disaster recovery from scratch on new hardware
- Automated backup scheduling and retention
See detailed procedures in sections below and references/backup-procedures.md for comprehensive guides.
Full Infrastructure Backup
Create complete backup with all components:
backup_dir="/home/dawiddutoit/projects/network/backups/full-$(date +%Y%m%d-%H%M%S)"
mkdir -p "$backup_dir"
# Backup Docker volumes
tar -czf "$backup_dir/pihole_data.tar.gz" \
-C /var/lib/docker/volumes/network_pihole_data/_data .
tar -czf "$backup_dir/caddy_data.tar.gz" \
-C /var/lib/docker/volumes/network_caddy_data/_data .
# Backup configuration
cp /home/dawiddutoit/projects/network/docker-compose.yml "$backup_dir/"
cp /home/dawiddutoit/projects/network/.env "$backup_dir/.env"
cp -r /home/dawiddutoit/projects/network/caddy "$backup_dir/"
cp -r /home/dawiddutoit/projects/network/config "$backup_dir/"
echo "Backup completed: $backup_dir"
What's backed up: Pi-hole data, Caddy certificates, configuration files, secrets (.env)
Restore Full Infrastructure
Restore from complete backup:
backup_dir="/home/dawiddutoit/projects/network/backups/full-backup-20260120"
# Stop services
cd /home/dawiddutoit/projects/network
docker compose down
# Restore volumes
docker volume rm network_pihole_data network_caddy_data
docker volume create network_pihole_data
docker volume create network_caddy_data
tar -xzf "$backup_dir/pihole_data.tar.gz" \
-C /var/lib/docker/volumes/network_pihole_data/_data
tar -xzf "$backup_dir/caddy_data.tar.gz" \
-C /var/lib/docker/volumes/network_caddy_data/_data
# Restore configuration
cp "$backup_dir/docker-compose.yml" .
cp "$backup_dir/.env" .
cp -r "$backup_dir/caddy" .
cp -r "$backup_dir/config" .
# Start services
docker compose up -d
Disaster Recovery
For complete rebuild on new hardware, see references/backup-procedures.md section "Disaster Recovery".
Quick overview:
- Install Docker on new server
- Restore configuration files
- Restore Docker volumes
- Start services
- Verify connectivity and certificates
Recovery time: 15-30 minutes

Expected Outcomes
Success:
- Full backup created with all components
- Backup size reasonable (< 500MB typical)
- Restoration completes without errors
- All services running after restore
- Configuration matches original
Partial Success:
- Backup created but missing some components (check manifest)
- Restore successful but services need manual restart
Failure Indicators:
- Backup fails due to permissions (need sudo for volumes)
- Restoration fails (volume path incorrect)
- Services don't start after restore (check docker compose logs)
Requirements
- Sufficient disk space for backups (recommend 2GB free)
- Root/sudo access for Docker volume access
- Backup storage location with appropriate permissions
- For disaster recovery: Same Docker version or compatible
Red Flags to Avoid
- Do not store .env backups unencrypted (contains secrets)
- Do not commit backups to git (contains sensitive data)
- Do not delete original backup before verifying restore works
- Do not restore to running services (stop first with docker compose down)
- Do not skip verifying services after restore
- Do not forget to backup .env file (critical for restoration)
- Do not rely solely on certificate backups (can be re-obtained)
Notes
- Backup Docker volumes while services are running (Docker handles consistency)
- .env file is most critical (contains all secrets and tokens)
- Certificates can be re-obtained if Cloudflare API token valid
- Pi-hole data includes blocklists, custom DNS, whitelist
- Full backup typically < 500MB (mostly Pi-hole blocklists)
- Restoration requires docker and docker-compose installed
- Test disaster recovery procedure periodically (quarterly recommended)
- Consider encrypted off-site backups for true disaster recovery
- Use backup-infrastructure script from existing skills if available
