I made a few Mercurial repositories by cloning individual folders from a large SVN repository. There was some data loss to the SVN repository and now these Mercurial clones are the only backup I have. Initially I thought I could just push them back to the SVN repository but I get the message no changes found for some folders and Could not push revision 864204e88250 because it had no changes in svn for at least one other.
Is there any feasible way to recover the SVN repository, or is my best bet to add new commits using the old messages/files (to preserve the log history, at least)?
