📝 Usage

Generating Exports

# Export all nodes and relationships
cypher-shell -u neo4j -p password \
  "MATCH (n) RETURN n" > exports/all_nodes.csv

# Export specific node types
cypher-shell -u neo4j -p password \
  "MATCH (cve:CVE) RETURN cve" > exports/cve_nodes.csv

Creating Backups

# Neo4j backup
neo4j-admin backup --database=neo4j --to=/path/to/backups/

# Graph analytics backup
cp analytics/graph_analytics.json backups/$(date +%Y%m%d)_analytics.json
