Logbackups problem on AG

  • The databases were fully backupped once?

    Databases are in full/bulk logging mode?

    Perhaps there are long running transactions/replications going on

    You could convert the maintance plan to a normal job to see what's going wrong.

    BACKUP LOG DATABASE X TO DISK='X:\AdventureWorks.TRN'

    backup log command[/url]

    Or use Ola's backup script as a replacement for the backup/index maintenance plans

  • Scripted or manual backups work fine it is the maint plan that give successful but no backups created.

  • Has somebody configured log backups to be done on one of the secondary nodes, or something like that?

  • Log backups has been configured on both but the backups are not getting created. I am getting the feeling I should just do it with a manual script.

  • Do you mean the AG has been configured to use "Any Replica"?

    Is there any sign of the backups in the msdb.dbo.backupset and msdb.dbo.backupmediafamily tables?

  • I changed it from Any to primary.

    No backups get created, as if the maint plan skips over the databases in AG.

  • You're not giving much information to work with! Where's the maintenance plan from, is there anything in the SQL log to indicate what's happening, etc?

  • Hi

    It is a straight forward maint log backup created in SSMS. I see no errors in the log. I assumed that this would be a stupid mistake on my side. like AG's not supported by the maint plan log backups.

  • Maintenance plans and AG work. I have had this problem before as well.

    Try secondary only in the Ag Group and "copy-only backups" in the maintenance plan.

    and yes when is fails it does not give much info in order to trouble shoot
