repo grows? Does it keep some sort of repository for each client
separately?I don't think so because if one deletes a WS the repo
shouldn't care but the extra hundreds on megs would stay there.
 
 'svn up' creates a temporary mirror of the working copy in the
 repository, compares it to the HEAD tree to perform a tree delta, then
 removes the temporary mirror.
 
 Thus even 'svn up' requires Berkeley DB to temporarily write new
 data. What you're witnessing is BDB logging all of these writes.
 Luckily, you can use 'db_archive' to throw away old logfiles. It's
 all documented in the subversion book.

So if I follow you correctly then what your saying is that if you have a
500MB working copy and 10 people in your group all do an svn update then
you've just added 5GB worth of log files to your hard drive?

I'd classify that as a scalability issue as well.

Mix.
