I love rdiff-backup. ;-) I will check out MineOS. Is there performance optimization to be had using Apache/MySQL for things? Seems like overhead, to me. I don't think this server is going to get to 100+ users or anything ... and if so, I'll spring for new hardware. Right now, I'm having an issue with my Debian kernel, I think, not allowing a java process to consume over 3GB. It seems like I might be better off limiting Bukkit to 1.5G and using the other 2G as a RAMdisk ... the server has 3.5G total and is an older machine that I am unlikely to upgrade unless absolutely necessary. Thanks for the tips!
