log backups fails

  • Hi,

    We are facing one issue with log backups ,it is failing continuously in one of the instance,and we found that it is because of one of the DB

    Is there any method to overcome this issue,we need the DB with the instance

    Is there any one helpme

  • What does it say in the error log? What recovery mode does this database have (if simple, you cannot backup logs)? What does "and we found that it is because of one of the DB" mean? Is this a maintenance job where all DBs are selected and it's failing because of one DB? Please provide more (much more) detail so we can help.

  • Sounds like somebody has setup a maintenance plan and selected 'all databases' instead of selecting just those databases that need to have log backups done. So the log backups for the databases that need it are being done but the job is failing because there are 1 or more database in SIMPLE recovery model specified in the maintenance plan.

  • That's what I'm thinking too. For months we had a MP running flawlessly, until someone changed the recovery option of a DB from full to simple. All the other DBs backed up fine but the plan would still show failure.

  • hi,there are around 20 dbs in this server,and all the databases recovery model is full.

    only the one db we are getting following messages

    Message

    Error: 3041, Severity: 16, State: 1.

    BACKUP failed to complete the command BACKUP LOG . Check the backup application log for detailed messages.

  • ....and what does the backup application log say?

    ....also check the error log in the span during the MP gets executed......give us some more information to analyze the situation.....:hehe:

  • Another possible reason for a log backup to fail is if you have never made a full backup of the database. As suggested, do check the SQL Server logs for more details.

    SQL BAK Explorer - read SQL Server backup file details without SQL Server.
    Supports backup files created with SQL Server 2005 up to SQL Server 2017.

  • Did you create this using the GUI or did you manually create the backup statement?
