Does your server OS not provide any way to see how much disk space is
used by a file or driectory tree?

If you're asking for something else, you'll have to give a more detailed

On Linux, du -s {repo directory} should tell you how much disk space a
repo is using. There's no way to tell how much space a specific
*branch* is using, though, because it's all wrapped in BDB database
files or whatever FSFS uses - there's no correlation between files in
the logical repository and the files on disk that represent the
repository. (At least, based on everything I've read about

In the repository, a URL-to-URL copy occupies a handful of bytes that
point back to the source of the copy, rather than actually copying
content. ("svn cp svn://path/to/source svn://path/to/dest")

This would be a WC-to-URL copy, in which case it should occupy about as
much space as the diffs plus the handful of pointer records required to
indicate the source URL(s) your WC started with.
