SQL-BACKUP Logshipping

I have problems with logshipping. After restore of the database, the logshipping is started. The first 2 restore-file are restored without problems. At time 15:25 (red color) we espected a resore-file from the "MASTERSERVER", but there was no file. After that the logsipping is out-of sequence.

How can I prevent this?
I did not get an error on the job-execution; The restore is scheduled by an SQL-job, but the job self did not fail

  • Hi Hans

    If there are multiple log backup files in the restore directory SQL Backup will read information from all of them and restore them in the correct order. This means that the database will not be out of sync.

    In your case the file was not copied across so if a file is missing the standby server will be out of sync. There is no way to prevent this included in the software as the restore will use any files it finds.

    What should be established is why there was no file. If the backup didn't take place then all should be ok as the next file to be copied across will continue from the last.

    A potential work around is to add a count to the file name so that the server are in sync. If the count number is out then the files would not be restored.


    As a note when setting up log shipping i would recommend having a full backup copied across each night. This will ensure that the databases are in sync each day, and reduce the amount of backup files needed for a restore. To automate this you can use the scripts in other posts but change the date field to:
    @datestamp = CAST(DATEPART(m, getdate())AS varchar(5))+ CAST(DATEPART(d, getdate())AS varchar(5))+ CAST(DATEPART(yy, getdate())AS varchar(5))
    This will remove the hours minutes and second so you know the filename for the restore process.
