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.


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".
