Right, and RAID mirroring isn't generally trying to minimise data loss, 
it's trying to maximise uptime.

Your rsync gives you something that RAID mirroring doesn't: a window to 
detect user error.

RAID mirroring gives something that your rsync doesn't: the ability to 
survive disk failure without any loss of availability.

Different goals.

A nice combination might be provided by using the ZFS filesystem, if 
you're on Solaris/OpenSolaris (or MacOS). Mirror the disks for 
availability, and use ZFS's snapshot facility for protection against 
fat-fingers, and even better without having to dedicate twice the disk 
space to do it (like rsync does).

That's how I'll be running SC on my new system...

cheers,
calum.
