Yep so I have unRAID for local redundancy (has the merged fs functionality with separate file systems as well as a parity drive). Also Crashplan (offsite) FTW. I then keep a local Crashplan backup copy on a second machine with the most important stuff like photos so it's basically instant backup for HD failure and slower offsite for house burns down situations.

I don't backup everything though. Media like Movies and TV shows I can deal with the loss of if the house burns down but it's nice to have some level of fail safe to cover a dead drive.
