Installing CrashPlan on Ubuntu 9.04 Server Edition
May 19th
Although rsnapshot is super for linux-to-linux backups, I’ve found CrashPlan to work very well as a backup solution for my family’s windows and mac boxes.
The CrashPlan installation works pretty well on ubuntu desktop edition, as all the necessary packages are already there. The server edition fails quietly, though.
Run these steps before you install CrashPlan, and everything should be smooth:

Preventing an external hard drive from idling on ubuntu
Jun 9th
I got a Seagate FreeAgent Pro external hard drive for backups (JWZ has a very straightforward article about this). It happily reformatted to ext3, and I kicked off an rsync of /home.
Because rsync figures out what files need copying before it copies them, and there are hundreds of thousands of files in my /home, there was more than a couple minutes of grinding on the local hard drive building a list of files to copy over. While this happened, the external drive idled into a “sleep” mode that ubuntu can’t seem to awaken it from.
This was slashdotted with an sdparm hack, but I believe this solution is better. Copy this new udev rule into /etc/udev/rules.d/50-local.rules (this is a new file that you will be creating):
