I would prefer to investigate: 1) Whether 'svnadmin pack' has never been run for this repository (assuming fsfs format). If so, this may be an opportunity for reducing disk space usage. 2) Whether Representation Sharing (data deduplication) is active for this repository. If not, then dumping and loading into a latest-format repository with Representation Sharing enabled (the default is enabled) may reduce disk space usage also. There are additional tuning options that could reduce disk space usage a bit more but the impact would likely be much smaller. If, on the other hand, you absolutely want to delete data from the repository so that it is removed from disk, as Daniel mentioned svnadmin dump with --include or --exclude (or svndumpfilter) do exist. You can read about them in the help text ('svnadmin help dump') and they are also documented in the SVN book: https://svnbook.red-bean.com/en/1.7/svn.reposadmin.maint.html#svn.reposadmin.maint.filtering WARNING: Please carefully read the *entire* section, especially the part about the caveats and gotchas (the last three paragraphs in that section). By filtering repository history, unless you carefully account for these "gotchas" you could introduce problems that might not be discovered immediately. VERY IMPORTANT: Before attempting *anything*, be sure you have complete, up-to-date, working *BACKUPS* of your full repository, and that you can restore it successfully. I certainly hope you already have backups, and yes this does mean that significant additional storage space is required. Hope this helps, Nathan
