但是必竞是PC机，故障的机率会大一些�?<span style="color: red">���其是硬�?/span>--数据的心脏，但是坏的可能性也是最大的�Q�这可真是一件头大的事情�?br />
当然可以用raid实现�Q�raid卡也需要主板的支持�Q�pc机的��L��支持raid的好像也不多�Q�而且raid做阵列也挺麻烦的�Q�恢复的时候也不简单�?br />
而且一但raid卡坏了，那还真是个大的麻烦，要去��C��块一��L��raid卡，旉���长了�q�真不好��C����L���?nbsp;<br />
<br />
<br />
其实了解了数据库的恢复机�Ӟ���q�个问题也好办，可以用以下方法实玎ͼ�我感觉这个方法比raid���单多�?nbsp;<br />
<br />
1.最���用两块���盘�Q�一块存放数据库的数据文�Ӟ��一块存放数据库的日志文�?nbsp;<br />
2.�Ҏ��据库要做一�ơ完全备份，备䆾可以和日志文件放在一块硬盘上&nbsp;<br />
3.打开数据库的完全日志 要做的就以上�q�些�Q�是否很���单�?br />
<br />
<br />
以上我是针对sqlserver来操作的。而且把数据文件和日志文�g分别攑ֈ�不同的盘上还可以提高性能�Q�一举两得�?nbsp;<br />
�q�样�Q�不���其中哪块硬盘出问题�Q�都可以实现数据恢复 如果放数据文件的���盘损坏�Q�你可以用完全备份和日志文�g来恢复数据�?br />
如果日志文�g���盘损坏�Q�不影响使用�Q�换块新的就OK。当然两块同时坏了就完了�Q�不�q�机率太���了吧，哈哈
