Msg 35295, Level 16, State 1, Line 1
Log backup for database “MyAppDB” on a secondary replica failed because the last backup LSN (0x0016ff11:00032258:0001) from the primary database is greater than the current local redo LSN (0x0016ffec:0006ee28:0001). No log records need to be backed up at this time. Retry the log-backup operation later.
