Preventing the nightly backup from disturbing the cache
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
