无牙能说说Symantec V-Ray 技术不？
无牙能说说Symantec V-Ray 技术不？:mrgreen: Symantec V-Ray 是赛门的一个正在申请的专利（不知道有诶有申请下来）.这个是官方的一个简单说明：
Symantec is introducing Virtualization Ray (V-Ray):Visibility for Virtual environments. Just like a doctor’s X-Ray gives visibility to see what is inside, Symantec’s V-Ray allows companies to see into VMs so they can see what’s inside so they can secure, protect, backup and recover virtual machines.
V-Ray visibility is delivered in across of Symantec products for virtual environments:security, storage, backup, etc. because virtualized data it real data and virtual machines should be protected as well as physical machines. How do you avoid backing up huge amounts of wasteful redundant data?V-Ray for NetBackup and Backup Exec sees duplicate files and helps you avoid the redundancy.How do you secure your VMs while still running at full speed? V-Ray enabled endpoint security SEP 12 knows which files have already been scanned on other VMs and knows to how to skip that scanning and keep on going. How do you know how many VMs are running your environment?V-Ray enabled IT Management Suite supports quick and complete identification of all VMs active on your LAN.
Symantec’s V-Ray provides you the visibility needed to peer inside your VMs and understand how to protect these systems and run them at the highest possible service level.
说白了就是能够识别虚拟环境中的数据，提升虚机备份/病毒扫描/重删的效率。
举一个非常直观的例子。
假设你有一个windows的物理机，你把所有盘上的文件用dedup都备份一遍。 然后你用vmware convert或者SSR等工具，将这个物理机转成vmware的虚机。 然后通过vstorage API的方式再对这个虚机进行备份。
如果没有使用 V-Ray技术，这次备份的dedup rate是不会超过70%的。 如果使用V-Ray， dedup的rate能到达90%以上。

解释的很直观。
主要是重删用的咯。
