Mark,

There are many layers to technology like everything else. Do not assume 
because one understand one layer, that one understand the implications of 
the other layers.

A computer guy taught you about digital backups, correct? Computer guys 
wrote the S/W to support the digital image workflow, correct? Please do not 
insult us computer guys about stuff we know lots about. :)

Backups are not enough if you want your digital images to be usable for your 
life time. You actually have to read (and write) each image you have 
regularly to ensure that a) the image has not been corrupted due to bit rot 
and b) to convert it to a current format with current version of your 
preferred S/W package.

If you are not doing both, you might as well not bother with the backup. 

None of us, as an individual, can afford (financially) to repeat the BBC 
Domesday Project which was an excellent example of how not to handle digital 
media.
