    Truncate fail_reason to column length

    During create_backup failure handling, backup_update fails with
    DataError ("Data too long for column") if the fail_reason is
    greater than 255 characters. As a result, backup status is stuck
    in 'creating' state. This patch avoids the problem by truncating
    fail_reason to 255 characters before update.
