"Last week, I told you about my NAS purchase, and my desire to explore desktop applications for backing up your Ubuntu computer. From the administrative interface of my Buffalo NAS, I created a network share that I could access with the different systems in my office. It's an SMB share so that it can also be accessed from Windows if needs arise. I then permanently mount those shares as network file systems (though not NFS) on my Kubuntu Karmic system.

In general terms, DeltaCopy is an open source, fast incremental backup program. Let's say you have to backup one file that is 500 MB every night. A normal file copy would copy the entire file even if a few bytes have changed. DeltaCopy, on the other hand, would only copy the part of file that has actually been modified. This reduces the data transfer to just a small fraction of 500 MB saving time and network bandwidth. In technical terms, DeltaCopy is a "Windows Friendly" wrapper around the Rsync program, currently maintained by Wayne Davison. "rsync" is primarily designed for Unix/Linux/BSD systems. Although ports are available for Windows, they typically require downloading Cygwin libraries and manual configuration.
Energy efficiency is not related just to power (kWh) requirement, or cooling requirements, or performance (MIPs) - it pertains to all of these variables. And it's not just a data center issue - it is critical for organizations of all sizes and scopes. To get started improving your energy efficiency, use the Dell Data Center Capacity Planner to understand how your choices impact your energy use.
Using AppleJack, you can repair your disk, repair permissions, validate the system's preference files, and get rid of possibly corrupted cache files. In most cases, these operations can help get your machine back on track.
