Server Snapshots

ssh root@your-server-ip

cd /opt/apps
docker compose down
# Repeat for every stack on your server
# Your apps are now offline

# List all volumes
docker volume ls

# Export each volume one by one
docker run --rm -v myapp_data:/data -v $(pwd):/backup \
  alpine tar cvf /backup/myapp_data.tar /data

# Repeat for postgres_data, redis_data, uploads, etc.
# 10 volumes = 10 commands

# PostgreSQL
docker exec postgres pg_dumpall -U postgres > postgres_backup.sql

# MySQL
docker exec mysql mysqldump -u root -p --all-databases > mysql_backup.sql

# MongoDB
docker exec mongo mongodump --out /backup
docker cp mongo:/backup ./mongo_backup

# Redis
docker exec redis redis-cli BGSAVE
docker cp redis:/data/dump.rdb ./redis_backup.rdb

# Different command for every database type!

# Find and copy all docker-compose files
find /opt/apps -name "docker-compose.yml" -exec cp {} ./backup/ \;

# Copy .env files (don't forget these!)
find /opt/apps -name ".env" -exec cp {} ./backup/ \;

# Copy nginx/traefik configs
cp -r /etc/nginx/sites-available ./backup/
cp -r /opt/traefik ./backup/

# Crontabs
crontab -l > ./backup/crontab.txt

# Create tarball of everything
tar cvf server_backup.tar ./backup/

# Encrypt with gpg
gpg --symmetric --cipher-algo AES256 server_backup.tar
# Enter passphrase twice
# Don't forget it!

# Or with openssl
openssl enc -aes-256-cbc -salt -pbkdf2 \
  -in server_backup.tar -out server_backup.tar.enc

# Install AWS CLI if not present
apt install awscli
aws configure  # Enter credentials

# Upload to S3
aws s3 cp server_backup.tar.enc s3://my-backups/

# Or use rclone for other providers
rclone copy server_backup.tar.enc remote:backups/

# Download backup
aws s3 cp s3://my-backups/server_backup.tar.enc .

# Decrypt
gpg -d server_backup.tar.enc > server_backup.tar

# Extract
tar xvf server_backup.tar

# Restore each volume manually
docker volume create myapp_data
docker run --rm -v myapp_data:/data -v $(pwd):/backup \
  alpine tar xvf /backup/myapp_data.tar -C /

# Import databases
docker exec -i postgres psql -U postgres < postgres_backup.sql

# Restore configs, update domains, restart everything...
# This takes HOURS
