I have log shipping setup and today we started getting the following warning alerts. The backup says they are successfull on the retry but the retores are failing saying that the backups contain no lsn info and are not encrypted which in fact they are. Below are the to logs from the backup and retore jobs.

    Hi Toeho,
    The reason for the retries is that the amount of free contiguous memory is very low - currently 19.4MB.

    If you are using any keywords such as THREADCOUNT or FILECOUNT, it could be that SQL Backup then requiers more contiguous memory than is available, so attempts a retry with the MAXDATABLOCK keyword at half the previous value (down to 65536, the minimum).

    The simplest solution to resolving the first error is to restart the SQL Server instance, this will clean up any fragmentation that has occurred in the SQL Server memory space and the backup should succeed first time.

    As for your second issue, that seems rather strange, I will look into this one further and will follow up once I've investigated it further.

    Thanks,
    Jason

    My issue with the first error is that Sql Backup is telling Sql Server that a successfull backup has taken place but when Sql Backup tries to use these files it is unable to do so thus breaking the log chain. At this point I have two issues First I can not do a point in time recovery since 2:55pm yesterday and Second for my DR solution to work I now have to ship the tape that has the full backup (150gb backup file) to the DR site and then start rolling the logs to catch up again.

    Not sure if this is possible but it would be nice if Sql Backup was sure the backup file had been written out before it acknowledged to Sql Server that a sucessfull backup had taken place.

    In the case of the restore, the problem appears not to be with the backup portion, but with the LSN information written afterwards.

    It is possible to restore each log individually, and this should restore correctly; but without valid LSN information it would not be possible to do "batch" log restores as you are trying to perform.

    Sorry to disagree - when running the following command I get the error below - It would appear that the backup files are corupted


    EXEC master.dbo.sqlbackup N'-SQL "RESTORE LOG [PRD] FROM DISK = ''G:\Logship\bad\PRD_10242007_145501_LOG.sqb'' WITH MAILTO_ONERROR = ''xxx'', ERASEFILES = 2, NORECOVERY, FILEOPTIONS = 1 , MOVETO = ''G:\Logship\Applied'', PASSWORD = ''xxx''"'

    Hi,
    I would agree with your thoughts given that last log; it does look like something has happened to the file.

    Out of interest, what compression level were you using during the backups? If you were using compression level 3, you may want to try dropping to compression level 2.

    I agree that the response from SQL Server indicating the backup was successful is rather concerning, I'll look into it further and try and establish what is going on.

    Thanks for your feedback,
    Jason

    We are using compression level 3

    At this point I have change the job script and moved compression level to 2 and removed the THREADCOUNT option. Should this create some stability in the backup job when the memory becomes fragmented or should I also look at setting the MAXDATABLOCK option as well??

    Another bit of information. My full backup had the memory issue last night and was supposably successfull on the first retry basied on the logs but I wanted to validate the backup before I sent the tape to the DR site. When I try opening the backup files via the GUI there is a red X in the ok column and it does not give me the oportunity to decrypt the files. Again the backup looks to be successfull from the log and from SQL. I belive there is a major bug here that needs to be addressed. I have over 150 sql servers with almost 1000 databases and can not validate each backup every day. Hope you understand my growing frustration.

    Hope this is helpful, curious as to why the backup log says it is successfull but all the verifications say otherwise?? Is it safe to assume it the backup is not successfull on the first pass then it will not be successfull even tough the log says it is????

    Here is the log from the full backup:

    To answer the questions in turn (since there are a few seperate ones):

    There is an issue with Compression Level 3 on some systems that is causing the backup to fail or be incomplete (as is the case in your latest log). Changing to level 2 should resolved any issues there.

    Some details on the THREADCOUNT keyword and memory usage is covered in another post here: http://www.red-gate.com/messageboard/vi ... php?t=5871

    If you are running that short of memory that you need to start using MAXDATABLOCK on a regular basis, your memory space is pretty fragmented. The simplest solution at this stage would be to restart the SQL Server instance when possible.

    In the GUI, if you hover over the red X it should explain why it's failed... that information will be quite useful in identifying why it doesn't like that backup. The missing LSN information in itself is an issue, but it won't cause the restore step to fail.

    Hope that helps,
    Jason

    Hovering over the red X provides the following
