[time-nuts] While we're discussing backups...

[Robert Vassar]

Just a quick thought.  I saw at least one person mention RAID, and  
another mention multiple copies of the same data.  A true backup copy  
is off line.  RAID does not protect you from an accidental delete,  
virus, etc... Multiple copies only spreads the risk around.


I backup to a USB hard disk.  I plug it in, backup, unplug it, de- 
cable and park it in a filing cabinet.  The disk spends 99.99% of  
it's life powered off.  It should last a decade or more like this,  
but I buy a new disk to replace it every 5 years, regardless if it  
needs it or not.  Really critical stuff goes on a CD-R, stored flat  
in a jewel case, and goes in the safe deposit box.
