CrashPlan is an automated backup system that does the job, but it's not without its pitfalls. The software offers a cross-platform backup solution that's reliably easy to use once you configure the software. Installing it to your Linux system, however, is anything but user-friendly. More than a few Linux users will emerge looking for a less-finicky solution. In addition, while the developer, Code 42, appears to adhere to the open source philosophy, you will face a big challenge if you try to locate the source code.
