- exclude the folder the repository resides in from your filesystem
- setup a routine that dumps the repository once in while (e.g.
Sunday night) to a different folder (like e:\reposbackup) and include
that folder in your filesystem backup;
- setup a post-commit hook script to do incremental dumps after
every commit to the reposbackup folder;
- finally have a routine that wipes both full and incremental dumps
once in a while (perhaps after the Sunday night full dump *and*
successful filesystem backup, perhaps less frequently, e.g. a
strategy that keeps at least the full dumps for a month or so on
your disk). You just don't want to collect all these dumps forever.

Read the book for both dumping as backup strategy and hook

In the beginning I had test repositories on another machine mapped
as M:\ to my notebook. Though creation of the repository works
fine over the LAN as do svnadmin commands the first access with
SVN (svn checkout/import/update) corrupts the repository. This is
on Win2K systems, so YMMV.
