先来看下ERRORLOG中记录了些什么
2016-11-11 02:00 差异备份失败，原因是磁盘空间不足
2016-11-11 02:10~2016-11-11 03:30 日志备份/10分钟，成功
2016-11-11 03:40~2016-11-11 03:50 日志备份/10分钟，失败，原因是磁盘空间不足
2016-11-11 03:55 Logfile encounter Operating system error 112~transaction log is full
数据库：完整恢复模式，日志文件增量为50MB，不限制最大文件大小
备份策略：完整备份/1天+差异备份/2小时+事务日志备份/10分钟
数据库文件保存在G盘，数据库备份文件同样保存在G盘
...G盘可用空间不足，差异备份失败，后续几个日志备份逐渐占用剩余空间，直到剩余空间放不下单次日志备份文件。日志不能被截断，事务持续进行，日志文件自动增长，但剩余空间不足50MB，增长失败。事务日志已满，所有涉及日志写入的操作失败。
存在问题
1、数据文件、日志文件、备份文件存放混乱
2、ERRORLOG中错误日志、磁盘可用空间没能及时预警
