Possible backup solutions
There are many different backup solutions that we can deploy for you to ensure they your data is safe. They start at the cheaper options and go up, depending on what level of paranoia you have will determine which you should go with. Each of them has their own advantages and disadvantages. Regardless of the option that you choose it is always advisable to download the site to your local computer occasionally, especially if the site contains very important information. This information was originally for use with Total Server Solutions but it is a good general guide for people thinking about backups.
The first and cheapest option will cost $0 if you have a secondary drive in the server. That option simply uses the backup feature within the control panel to save the backups directly to the 2nd drive. Many clients choose this because it is cost effective and is reasonable safe. The downside is that if for some reason both hard drives crash at once your data is gone, while this is rare it is possible. If you have any information of significant value I would highly suggest against this method.
RPM Kernel Upgrade
This is a very simple guide meant for people unfamiliar with upgrading kernels on a linux system. It is fairly simple to follow and I have done this on many servers so if you take your time and read though it you should have no problem. I take no responsibility if something goes wrong on your server because of this! This guide is formated for a RHEL server but if you understand the concept it can be applied to any rpm kernel.
Updated August with new versions
The kernel versions are constantly changing so this guide may fall out of date from time to time. The important thing to remember is when you are doing the up2date –download simply look at the version that is downloaded. That is going to be the latest version and in turn the version you want to install and boot to. RHEL or CentOS 5 follow the same basic method.

NFS Crash course
I wrote up a quick guide to setting up NFS awhile back but never published it. It is not exactly a nice and clean format but it is exactly what you need to be reading if you want a quick way to setup NFS between two servers. For the purpose of the guide I have added directions for the APF firewall, obviously anything else will work fine.
First make sure the rpms are install
up2date nfs-util portmap
yum install nfs-util portmap
Now start the service:
service portmap start
service nfs-util
How to significantly cut back spam with cPanel 11 RBLs
Along with the many other GUI enhancements that have come with the new version 11 there have been some MAJOR improvements in how spam is handled. While cPanel has always remained an easy to modify system many people do not like to start modifing configuration files. Those people will be happy to learn that now cPanel 11 includes support for RBL support.
