【Docker compose】基于宿主机的Neo4j自动备份

1、开启自动备份

在宿主机执行：

1. bash #{lakehouse_home}/neo4j_cron.sh  

复制代码

自动备份开启如下日记：

1. Fri Mar  7 01:59:53 UTC 2025 - Checking if cron job already exists.  
2. Fri Mar  7 01:59:53 UTC 2025 - Adding new cron job.  
3. Fri Mar  7 01:59:53 UTC 2025 - Cron job added: 0 23 * * * bash /root/run/neo4j_backup.sh >> /var/lib/neo4j/import/cron_backup.log 2>&1  
4. Fri Mar  7 01:59:53 UTC 2025 - Checking if cron service is running.  
5. Fri Mar  7 01:59:53 UTC 2025 - Cron service is already running.
