What is interesting with svnrdump is that it is efficient to generate a
"partial" dump, in term of revision range and selected path !

What "svnadmin dump" is not able to do without scanning a large part of
the full repository (10 GiB)...

Indeed you were right. As there is no merge tool for format 3 dumps, I
decided to rsync over ssh the repository and run svnadmin dump on my
workstation to avoid disturbing users.

Thank you for that tip
