I don't know how much that matters, if I'm going to do a compressed tar
Doing a bzip2 (or even only gzip) takes more time than getting the data out of
the repository, no?

Yes, it *may* be worthwile that some directory is updated, and a tar is taken
from there.

Hmmm, the change rate? Good question. Normally small, but if eg. openoffice is
replaced, thats 100MB in a single change...

Later in this thread a svntar is mentioned; it seems to work.

Thank you for your thoughts!
