Hi 六月i,
这是磁盘i/o的问题,表示当前备份正在等待磁盘i/O完成。任何长时间运作的数据库操作(备份,还原),如果发生非常缓慢地处理数据,都有可能进入到这种等待状态。如果你的数据库很大或者当前工作负载很大的话,这个状态是正常状态,你只能等待。
如果你的数据库不是很大且工作负载不大,建议你首先查看windows event log 和error log看看是否有关于i/o的警告或者错误,或者通过performance moniter查看Average Disk sec/Read Average Disk sec/Write Average Disk Read/Write 这些参数调查磁盘性能。
当前问题的处理办法:降低工作负载,将备份的时间换到非高峰时期,升级磁盘,将数据文件保存在不同的磁盘上以达到并行i/o的效果,有可能的话启用备份压缩。
Hope this could help you .
Best regards,
Dedmon Dai
