The database(s) were recently restored hence they got skipped from the log backup


  1. Follow the instructions provided in the link below to obtain job logs.
    How to collect the detailed job logs
  2. Extract the logs and go to Phoenix<YYYYMMDD>_<timestamp>.log file to see the below traceback in the logs.

  1. Log on to the SQL server which hosts the SQL instance
  2. Connect to the SQL Server Management Studio
  3. Execute the query to find out restore history of the database which is skipped from the log backup
    select * from msdb.dbo.restorehistory where destination_database_name like '%<database_name>%'
    Reference : restorehistory (Transact-SQL)
