写过滤问题 [英] Write Filter Question

问题描述

我对写过滤器知之甚少，甚至不确定是否需要使用它们。我已经阅读并阅读，但仍然无法将头缠在他们身边。如果您能指出我们易于阅读的细分，请这样做。

但是现在，我没有使用任何写过滤器。我只是投入FBWF，因为EWF w / HORM与Windows启动环境发生冲突。

我们的机器使用SQL并且不断写入和读取数据库，我不需要擦除它out（因为我读了一个写过滤器保存写入，直到你重新启动）。

那么使用写过滤器有什么好处，任何性能优势？我应该使用哪一个？安装FBWF并且没有使用它会有什么损害？

 

解决方案

Sean可能会更好地解释这些但是...

写过滤器的好处是保护。它将保护操作系统免受损坏，意外搞砸和病毒。如果您将固态介质用于硬盘驱动器，它也会有所帮助，因为固态介质具有有限的写入功能
您不希望操作系统在不需要时不断写入。因此，写过滤器会将数据写入RAM，直到您告诉它将写入的文件提交到硬盘驱动器。

在图像中使用FBWF而不使用它不会伤害任何东西。如果在您的情况下，您希望不断写入数据库并启用FBWF并保护操作系统，则可以指定FBWF无法保护的目录。

希望这会有所帮助。

I dont know much about write filters and not even sure if I need to use them. I've read and read and still cant get my head wrapped around them. If you can point me to an easy to read breakdown of them please do so.

But right now, I'm not using any write filters. I just toss in FBWF, because EWF w/HORM conflicts with windows boot environment.

Our machines use SQL and are constantly writing and reading to the DB, I dont ever need this to be wiped out (as I read a write filter saves the writes until you restart).

So is there any benefit to using a write filter, any performance benefit? and which one should I use? Is it hurting anything have FBWF installed and not using it?

 

解决方案

Sean will probably be better at explaining these but...

The benefit of a write filter is protection. It will protect the OS against corruption, accidental screw ups and viruses. It will also help if you are using Solid State Media for your hard drive, because it Solid State Media has limited write capabilities you do not want the OS constantly writing to it when it doesn't need to. So instead the write filter will write the data to the RAM instead until you tell it to commit the written files to the hard drive.

Having FBWF in the image without using it does not hurt anything. If in your case you want to constantly write to a database and have FBWF enabled and protecting the OS, you can designate directories that FBWF will not protect.

Hope this helps.
