Well, just because they aren't likely to change
doesn't mean that they shouldn't be backed up, right? 

To me, the subversion repositories are the my primary
backups of all my personal files.  This include my
photo collection which I do not anticipate changing
(but it does get reorganized and I certainly don't
want to risk losing anything while moving stuff
around).  Afterall, many people put that stuff on
CDRs, but they will degrade in a few years and be

I have a special svn repository for stuff that I'd
like backed up currently, but do not anticipate
actually having to have any history for.  This
repository is called 'volatile'. :)  I use this for my
inbox and various other junk files (many dot files). 
The idea is that at some point I could just make a new
volatile repository and delete the old one if it gets
too big.  This allows me to keep one backup strategy
for everything, svn, but I have things split into
various bins (reposistories) depending on the use, and
I make heavy use of subversion externals.  

Ideally if subversion ever allows it, a truncated
feature would be nice for something like my volatile
repository.  If I could just say truncate history up
to 3 months ago, that would be cool!
