Storing large amounts of medium-sized binary files in Subversion

Hello,

how good/bad an idea is storing large amounts of medium-sized files
(think Yum/RPM repositories with full CentOS/EPEL releases) in
SVN for rollback and other purposes?

I've got the feeling that the amount of disk space consumed for
deprecated versions alone should be preventive; making backups etc.
unnecessarily hard.

Are there other reasons not to do this? How would you build an argument
about this? Can you make this an FAQ answer?

Cheers,

   Andreas
