Symptoms
Consider the following scenario:
-
You enable the AlwaysOn Availability Groups feature in Microsoft SQL Server 2012.
-
You enable the Log Shipping feature on some databases that are in an AlwaysOn availability group.
-
You have a monitor server to monitor the log shipping.
In this scenario, the backup job is running correctly. However, you receive the following error message:
Error: 14420, Severity: 16, State: 1
The log shipping primary database %s.%s has backup threshold of %d minutes and has not performed a backup log operation for %d minutes. Check agent log and logshipping monitor information.
Cause
The issue occurs because the log_shipping_monitor_primary table is not updated when the sys.fn_hadr_backup_is_preferred_replica system stored function returns "0".
Resolution
After you apply this fix, the last_backup_file in the table log_shipping_monitor_primary column will be updated together with a dummy file name to resolve this issue.
The issue was first fixed in the following cumulative update of SQL Server.
