Does using the file screen functionality on File Server Resource Manager add a performance hit?

tegenius used Ask the Experts™
Hey everyone,

We're looking at setting up a file screen on our file clusters to look for decrypt*.* in the hope that we can catch it early. I have a few questions about this method.

1. Does FRSM need to be installed and setup on EVERY cluster node.
2. Does using this file screen feature add a performance overhead and slows down file/folder moving and copying?

Try it out. It will be a performance hit, but who knows if you can feel it? Depends on many factors  of your storage. About where to install it: I didn't work with FS clusters, sorry.

About the idea itself: consider to implement applocker or software restriction policies. That together with regular backups and you have nothing to fear.
