| ## 📝 Usage |
|
|
| ### **Generating Exports** |
| ```bash |
| # 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** |
| ```bash |
| # 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 |
| ``` |
