ext3文件系统是否支持快照？ 如果是这样，这可以做到没有LVM的直分区吗？
“直分区”的例子如下：
Unlike a number of modern file systems, Ext3 does not have native support for snapshots - the ability to quickly capture the state of the filesystem at arbitrary times, instead relying on less space-efficient volume level snapshots provided by the Linux LVM. The Next3 file system is a modified version of Ext3 which offers snapshots support, yet retains compatibility to the EXT3 on-disk format 引用： http : //en.wikipedia.org/wiki/Ext3#Lack_of_snapshots_support
我build议使用R1Soft Hot Copy来获取文件系统的时间点快照。 使用此function，您可以在不使用LVM的情况下获得干净的快照。 这很干净，应该给你你要求的。
