Log backup failure

  • Hi All,

    Log backups for multiple databases in same server but different instances are keep on failing. Error log says its due to network path could not be find. But the same path was working for others.

    Kindly advice on this.

    Thanks

  • Used maintenance plan to create log backup which successfully ran previously.

  • Check that the backup server is visible from the places where the backup is failing. Check that the SQL Server service account has permission on the backup location.

    I also wouldn't recommend backing up to the root of a drive, it usually has more restrictions than a folder.
