"A perennial problem facing computer users is how to keep documents, pictures, music and other personal files synchronized between computers. Robust uni-directional solutions, like rsync, and bi-directional solutions, like unison, have existed for a long time. However, these tools require some degree of manual intervention on a periodic basis. Simplified tools like Dropbox and bittorrent sync have emerged as popular, useful and automated alternatives, but these rely on closed-source software, which could be subject to backdooring. Open source solutions, like OwnCloud, are gaining traction, but are these open source platform robust and easy enough to maintain for routine and daily use? Moreover, distributed and encrypted file systems, like Ceph, are increasingly easy to use, but many of these do not work between Linux and OS X or Windows operating systems. What are your experiences and thoughts?"

It's all those little things that add up. I did go around my house with a power meter (in the US they call it Kill-a-Watt, I think) and the it seems that most is from a lot of times "just a few watts".
I already have a VIA-based server, that runs the OS from flash storage and stores data on a HDD that is not spinning most of the time. (this configuration was after endless unsuccessful tweaking to prevent syslog/samba/etc. from modifying files on a HDD-based OS every few minutes).
It uses 13 W, which bugs me, but not quite enough to shut it down. I was curious to hear how you could run an Atom server at less than 2.5 watts.
I considered an ARM-based system, but I foresaw to much duct tape to get Gbit ethernet and the ability to drive a HDD over USB. Also, ARM seems to be a bit too slow to handle large file transfers over ssh.

Fair points.
I don't think you should "upgrade" to lower power consumption until closer to the end-of-life of your current system, however - you'll likely spend more on new hardware than you'll save in energy over the projected lifespan.

Did you try putting /var/log on a separate partition and setting the writeback time to a high value?

No, but /var/log wasn't the problem. Maybe I should have put the entire /var on a partition with different mount options. I retired this machine, so I'll never know...
