I am currently setting SQLBackup 5 on one server to do transactionlog backups. This has been running for a few weeks now, but I got this error today.
SQL Backup log file

Any ideas to what might have caused this error?

    Thank you for your post into the forum.

    I suspect that your SQL Error 8169 is due to the errors that created SQL Backup exit codes 742 and 760.

    For some reason SQL Backup was unable to obtain LSN data from the server's msdb database.

    SQL Backup tries to retrieve the LSN information from the backupset table to insert the retrieved information into the backup file's header.

    SQL Backup exit 915 indicates that SQL Backup failed to update the backupset table.

    When your log shipping backup job triggered, when there any other jobs running preventing access to the backupset table? Or other processes running preventing access tot the backupset table?

    Is this the only occurence of this error or you have had further errors?

    Many Thanks

    We do transaction logs once an hour, so it might have been jobs running at the same time.

    So far there has only been this one occasion, so no alarmbells going off yet :-)
