我的SQL服务器上运行了一个月工作。
它将所有在线数据库备份到“\ Backupserver \ e $ \ MonthEndBackups \”的位置。
Job在下面运行USP:exec [usp_dba_BackupDatabases] 3 (http://screencast.com/t/l7IS5TZK)
它在每个月的最后一天运行。
我们的数据库分散在多台服务器上,这项工作在这些服务器上运行,而且过去一直有效。
我们在同一台服务器(同一个SQL实例)上整合了所有数据库,这个作业似乎没有备份所有数据库。我不知道为什么?我的工作有失败的通知(电子邮件),也写入日志文件。
http://screencast.com/t/8ioTZdqEMg9x http://screencast.com/t/VI3d4GLBTGoX
但没有任何失败,因此日志上没有任何内容,也没有显示电子邮件通知。
我知道它不起作用,因为我没有看到文件夹中的完整备份。
这是日程安排:

可能出现什么问题?我没有在数据库中看到任何未备份的模式。有更大的数据库正在备份。
有人能想到为什么会发生这种情况吗?有什么方法可以解决这个问题吗?

答案 0 :(得分:2)
尝试使用以下选项(修复可能会破坏当前循环和also break sp_MSforeachdb
的选项,因为我已记录here和here以及corrected here) :
DECLARE c CURSOR LOCAL FAST_FORWARD FOR
-----------------^^^^^^^^^^^^^^^^^^
...
WHILE @@FETCH_STATUS <> -1
---------------------^^^^^
另外,please, please, please stop declaring VARCHAR
without length。
