I see a couple of problems here... firstly there is potential for
extortion. You lose your storage and want your data so you submit a
request to 'the network' to retrieve it. Doesn't matter whether the
person(s) holding your data can read it or not (it may be encrypted),
they can always refuse to hand it over. Sounds like a nice little
earner.


Also, you are not going to want a single copy of your data. You'll want
at least two. As will everyone else. To do this, the network therefore
requires capacity roughly equal to 3x the size of the data (1 'live'
copy on your machine, at least 2 other copies elsewhere). Yes,
compression may help, but not for already-compressed data such as JPEG
photos, MPEG videos, MP3/Ogg audio files, etc...

I don't see it working..
