Windows Open File Backup and VSS question

Hi guys,

It's the first time I have to work with this product and I'm trying to optimise the backups so they don't require so long.

My question is: Can I somehow successfully backup open files in windows file servers, without having to backup the "Shadow Copy Components:\" in the backup selections for a backup policy?

I've been googling around and I saw that you can go to the NBU console>Host Properties>Master server properties>Client attributes, add the relevant client and enable Windows Open File Backup. With that enabled, would the policy back up open files on the server if it was configured to back up all the drives and system state, but not the "Shadow Copy Components:\"?

Thanks!
