Security Notes

  • 🔒 All services bound to localhost only
  • 🔒 No external network exposure
  • 🔒 Development mode - add authentication for production
  • 🔒 Regular backups recommended
  • 🔒 Monitor disk usage on /data partition

Backup Procedures 

# Full DataOps backup
sudo mkdir -p /data/adaptai/backups/dataops/$(date +%Y%m%d)

# Backup each service
sudo rsync -av /data/qdrant/storage/ /data/adaptai/backups/dataops/$(date +%Y%m%d)/qdrant/
sudo rsync -av /data/dragonfly/ /data/adaptai/backups/dataops/$(date +%Y%m%d)/dragonfly/
sudo rsync -av /data/redis/ /data/adaptai/backups/dataops/$(date +%Y%m%d)/redis/
sudo rsync -av /data/janusgraph/data/ /data/adaptai/backups/dataops/$(date +%Y%m%d)/janusgraph/

sudo rsync -av /data/nats/ /data/adaptai/backups/dataops/$(date +%Y%m%d)/nats/

# Database dumps
pg_dumpall -h localhost -p 5432 -U postgres > /data/adaptai/backups/dataops/$(date +%Y%m%d)/postgres_full.sql
mongodump --host localhost --port 27017 --out /data/adaptai/backups/dataops/$(date +%Y%m%d)/mongodb_dump/

Monitoring & Alerts 

# Disk space monitoring
df -h /data | grep -E "(Filesystem|/data)"

# Memory usage
free -h

# Service monitoring
ps aux | grep -E "(qdrant|dragonfly|redis|janusgraph|clickhouse|meilisearch|postgres|mongo|chroma|nats)"

# Port monitoring
netstat -tln | grep -E "(17000|18000|18010|17002|9000|17005|5432|27017|8000|18222)"

Emergency Recovery 

# Stop all services
sudo pkill -f "qdrant|dragonfly|redis-server|java.*janus|clickhouse|meilisearch|postgres|mongod|chroma|nats-server"

# Restore from backup
sudo rsync -av /data/adaptai/backups/dataops/LATEST/ /data/

# Restart services (refer to individual connection guides)
# ...
