I, at least, don't.

Well, that might be a problem.

The search for modified files relies on the time stamps. If, in your
modified copies, the modifications happened before the initial full
backup these changes won't be backed up.
Even worse, IMO, is that using your approach you have no record of
where your backups actually cam from. You can't know if a certain job
backed up //win/template or //win/copy1. That makes restoring a
distinct file quite impossible without external book-keeping.

No simple solution... what you could think about is using a program
like backup PC to collect the data in a central site, using hard links
as far as possible, and then backing up that repository.

Nothing new as far as I know, i.e. it is on the projects list, but no
schedule regarding actual implementation.
