Yes, it sounds like a lot. However, if you think about the time you 
need to file and maintain (without any backup except prints made) 
film, in slide, B&W negative and colour negative form for multiple 
formats, the digital stuff takes up a small fraction of the time 
considering the number of images.

Scanning can be used for backup, but then you got the whole digital 
archiving thing again, and the files are a lot bigger for a given 
quality level than RAW format.

And if my house burns down, I still have most of my images.
