sql-server - SQL Server 作业保持在 run_status = 4

Question

我有一些 SQL Servers 2016 标准版。有备份的维护计划。特定作业运行此维护计划。工作的结果是成功。但工作分为两个步骤。

**-- First step ( Success )** 
Date        21.04.2021 1:00:00
Log     Job History (DB-backup.Subplan_1)
...
Message
Executed as user: NT Service\SQLSERVERAGENT. The step succeeded.

**-- Second step ( Success ), but in dbo.sysjobhistory I can see run_status as 4 ( In Progress )** 
Date        21.04.2021 1:00:00
Log     Job History (DB-backup.Subplan_1)
...
Started:  1:00:00 AM
DTExec: The package execution returned DTSER_SUCCESS (0).

我已经尝试在测试服务器上恢复数据库，一切正常。

为什么第二步仍然在run_status = 4？
