客户可以配置备份，物理备份要开启归档，归档开了没

select sydate；检查下服务器时间

可以查看一下定时作业的错误原因

SELECT *
FROM SYSJOB.SYSSTEPHISTORIES2 A
WHERE (SELECT COUNT(*)
          FROM SYSJOB.SYSSTEPHISTORIES2 B
         WHERE B.NAME = A.NAME
           AND B.EXEC_ID >= A.EXEC_ID) <= 10
ORDER BY A.START_TIME DESC,A.NAME;

点击作业看一下执行历史，查看报错信息
