Hi all, I have a server with 4GB of memory and a workload that allows it to work mostly from memory without a lot in the way of disk reads. However, every night the backup distrurbs that situation by reading every file on the system. Is there a way to prevent this from happening? I'd like to be able to tell the kernel, hey this program is going to be reading a bunch of files serially, so please don't cache the data. Is that possible? Thanks, Steve
