A home backup solution
At home I have a Seagate Mirra Sync and Share server that I picked up for $300. It lives in a low-risk room. My family's computers are all set up with partitioned HDDs. The OS lives on one partition and the data lives on a different partition to protect it from the OS getting scrambled.
All directories that contain valuable data, on both partitions, and on all computers, are synced to the Mirra server. Any file that is added, or changed, on any computer is normally backed up to the Mirra within 10-20 seconds. The Mirra keeps all files for 8 versions back in case the file is scrambled by a user and saved in a scrambled state (the version system allowed my wife to recover a scrambled address book in 5 minutes by going back 3 versions).
Future plans are to move the Mirra to my shed thereby having it in a different physical building for better fire-risk, and to upgrade it to a Seagate BlackArmor NAS.
We live on a hill where floods are not a credible threat.
