I have a pretty simple disk setup in my desktop. Although I don't have a NAS in my home, or even a redundant RAID array in my desktop, I like to know that my home directory is backed up to at least two other physical disks.

I came across this blog post outlining a simple script to backup my home directory, and I modified the script slightly to meet my particular needs, and set up a cron job to run it in the middle of the night.
Here is what I came up with:
As always, I hope this helps someone else out.
