Personally, I wouldn't mess around with RAID, LVM, ZFS, etc.  Buy as much
storage as you need for online use, and backup important data frequently to
an offline drive that you store in a media safe (unless you can put a NAS
at a friend/neighbors house and do offsite backups over the wire).

I use rsnapshot to create backups with history so I can recover
deleted/modified files back several months, really important stuff is
uploaded to free cloud storage in addition to my local backup.

I have used RAID in the past, and never had it save me once (have had good
luck with drives)... while my backups have saved me many times when things
were deleted or changed (something RAID wouldn't have helped with anyway).
