This guide explains how to build and install a custom kernel RPM with FUSE support on Yellow Dog Linux 6. The guide is written based on my experience with YDL on an Apple XServe G4 using kernel-2.6.23-9 on ppc architecture. If your system is different then adjust the guide as required.
There are many tools available to help backup Linux systems to Amazon S3 but finding the right one to use can be difficult. Jeremy Zawodny made a good list of various S3 backup tools which is very helpful, if a little outdated. I experimented with a few tools, including some of the standard scripts published by Amazon but I found each had their own shortcomings.
One tool that is very simple to use is s3cmd which is a linux command line tool to upload, retrieve, and manage data in Amazon S3. The tool is written in python so should install and run on pretty much any modern linux distro and I have found it works very nicely and seems to be an ideal tool to use if you want to write a basic backup script.
