[LUNI] Critique my backup plans :)

[Mark Stuart Burge]

I would suggest a plan that keeps one of the backups off site at any one 
time if the data is critical.

If you have a 'one in / one out' system running then you can simplify 
the script to mount either drive an the same mount point.


Works pretty well with usb drives !

Would love to know if anyone has got a mondo / mindy based backup 
working well with removable drives.
