Data Scrubbing in archives and paranoia

     I moved
everything to ZFS several years ago after looking at the  design.

 Unfortunately, Oracle controls it now, and there aren't a whole lot of
 good
 inexpensive choices for that class of scalable storage. 
 It looks like there are several ports to non-Solaris platforms, at various stages of
maturity.  - Ian

Having read up on ZFS I am very impressed with the level of paranoia. Especially its
distrust of what has become "industry standard" solutions to data storage
reliability. E.g.:

* ZFS can not fully protect the user's data when
* using a hardware RAID controller, as it is not able
* to perform the automatic self-healing unless it
* controls the redundancy of the disks and data.
* ZFS prefers direct, exclusive access to the disks,
* with nothing in between that interferes.

That's the level of paranoia that I want! I was always convinced the RAID controllers
are only specified to screw me over. I make the folks with tinfoil hats look like
wannabes.
