I have created the log shipping job, backup, copy and restore job occurs without any error. However in the secondary server, LSAlert job has errors:
Executed as user: NT AUTHORITY\NETWORK SERVICE. The log shipping primary database server.AbraEmployeeSelfService has backup threshold of 60 minutes and has not performed a backup log operation for 276 minutes. Check agent log and logshipping monitor information. [SQLSTATE 42000] (Error 14420). The step failed.
I have deleted log shipping completely, deleted all the rows in the logshipping related tables and restarted the process. Sqlserver agent error log is not relay anything about log shipping. I have scheduled the backup job at 12 am, copy at 12:05 am and restore at 12:35 AM
